Abstract:
Com o desenvolvimento dos grandes centros urbanos e o aumento das áreas impermeáveis, surge a necessidade de aumentar as áreas permeáveis, sem abrir mão do pavimento de concreto e ainda assim ajudar na drenagem urbana, tirando a sobrecarga dos sistemas de drenagem tradicionais. Desse modo, o objetivo desta pesquisa é comparar dois traços de concreto permeável com as mesmas características físicas e mesmas compactações, mas tendo como diferença o tipo de cimento a ser empregado que serão o CP II-E e o CP II-Z, ambos com 32 MPa de resistência, com isso serão analisadas quais as mudanças na resistência e na permeabilidade dos corpos de prova que podem ocorrer. Serão moldados em laboratório cerca de 6 corpos de prova para ensaios de resistência à compressão e mais 4 corpos para os ensaios de permeabilidade que seguiram as especificações da NBR 16416 com algumas adaptações e foram cronometrados o tempo que o corpo de prova demorava para absorver certa quantidade de água e usando uma fórmula disponível na mesma norma. Os resultados indicam que não houve diferenças significativas entre os traços comparados, porém a resistência de ambos foram superiores às observadas em outras pesquisas e notou-se que os traços feitos com o CP II-Z tiveram uma ligeira vantagem, mas ainda ficam empatados com o outro traço. No quesito de permeabilidade, ambos têm um ótimo desempenho, pois atendem aos critérios mínimos da NBR 16416. Conclui-se que a comparação entre esses dois cimentos não mostrou tantas diferenças significativas, porém foi observado que a compactação e cura são elementos fundamentais para agregarem resistência aos pavimentos drenantes. Com isso, é possível ampliar o leque de aplicações para que no futuro se possa adotar o pavimento permeável até mesmo em vias públicas e rodovias. A STUDY OF THE RELATIONSHIP BETWEEN STRENGTH AND HYDRAULIC CONDUCTIVITY OF THE PERMEABLE PAVING ADDED WITH POZZOLAN ABSTRACT Along with the development of large cities and the increase in impermeable areas, it raises the need for permeable areas expansion without forgoing the concrete paving and after all promoting urban drainage in order to unburden the traditional drainage systems. Accordingly, this study sought to compare two traits of permeable concrete with the same physical characteristics, the same compaction, although they differ in the type of concrete to be applied, they are CP II-E and CP II-Z, both 32 MPa resistant, hence possible changes to occur in strength and permeability of the specimen will be analyzed. In the laboratory, six specimens will be mold for compressive strength testing, and four extra specimens for permeability testing following NBR 16416 standard with some adaptations, we measured the time the specimen takes for absorbing an amount of water, as well as an available formula following the same standards. The results suggest that there were no significant differences between the traits when compared. However, the strength for both was higher when compared to other studies, it was noticed that traits made with CP II-Z presented a slight advantage, nevertheless, they are similar to the other trait. Regarding permeability, both had a great performance, since they meet the minimum NBR 16416 standards. We concluded that the comparison between those concretes had not presented significant differences, though we observed that compaction and drying are key elements to add strength to draining concrete paving. Hence, it is possible to broaden applications in order to adopt permeable paving even for public roads and highways. Keywords: Permeable paving. Drainage. Concrete.

El campus universitario presenta problemas hídricos: encharcamientos en época de lluvias, desabasto y cortes de agua. Este trabajo evaluó la posibilidad de restaurar el ciclo hidrológico urbano mediante tecnologías lid en una zona con baja precipitación. Se establecieron las siguientes variables hidrológicas para el diseño: precipitación anual para un año muy seco (181.1 mm), precipitación promedio de 15.09 mm, con máxima de 53 mm y mínima de 0 mm. Se calculó el volumen de agua de lluvia recolectable en azoteas, el coeficiente de escurrimiento (concreto, C= 0.9) y el consumo promedio diario en sanitarios. Se dimensiono el sistema de almacenamiento y el número de días en que se satisface la demanda como agua no potable. Se calculó el volumen de escurrimiento medio (Vm) en estacionamientos y vialidades con superficies asfálticas (C= 0.8) y andadores de concreto (C= 0.9) y se comparó con el Vm si se sustituyeran con pavimento permeable (C= 0.7). Además, se determinó la capacidad de infiltración en áreas verdes.

RESUMO: O processo de urbanização das cidades sem o adequado planejamento de uso do solo provoca uma crescente impermeabilização deste, levando a constantes cheias nos centros urbanos. Entende-se que os sistemas tradicionais de drenagem resolvem apenas parte do problema, pois não agem nas causas mas somente nos efeitos. Nesse sentido o presente trabalho tem como objetivo avaliar o desempenho do pavimento permeável em relação à capacidade de infiltração das águas pluviais, visando à redução do escoamento superficial em áreas urbanas; para isso foi realizada a simulação chuvas para obter o escoamento por meio da equação de precipitação de Palmas-TO, onde foi possível aferir parâmetros de infiltração e escoamento; também foram produzidos e ensaiados blocos em concreto poroso para avaliar sua capacidade de infiltração. Na simulação efetuada sobre o pavimento permeável em blocos intertravados observou-se que ocorreu uma absorção da precipitação nos 9 minutos iniciais; já na simulação realizada sobre os blocos vazados percebeu-se que neste praticamente não ocorreu escoamento superficial. Os blocos em concreto poroso demonstraram uma ótima capacidade de infiltração, conseguindo comportar em seu interior 7,2 litros, o que significa uma infiltração instantânea de 7,2mm de chuva. ABSTRACT: The process of urbanization of cities without the adequate planning of land use causes a growing waterproofing of this, leading to constant floods in urban centers. It is understood that traditional drainage systems solve only part of the problem, as they do not act on causes but only on the effects. In this sense, the present work aims to evaluate the performance of the permeable pavement in relation to the infiltration capacity of rainwater, aiming at reducing surface runoff in urban areas; for this, the simulation was performed rains to obtain the flow through the Palmas-TO precipitation equation, where it was possible to measure infiltration and flow parameters; blocks were also produced and tested in porous concrete to assess their ability to infiltrate. In the simulation carried out on the permeable pavement in interlocked blocks it was observed that precipitation was absorbed in the initial 9 minutes; already in the simulation carried out on the leaked blocks it was noticed that in this practically no surface runoff occurred. The porous concrete blocks demonstrated an excellent infiltration capacity, managing to accommodate 7.2 liters inside, which means an instant infiltration of 7.2mm of rain.

Abstract:
The results of a 1.5-yr laboratory study and field investigation of three Virginia bridges are presented. Specimens with fly ash, slag cement, silica fume, silica fume with a corrosion inhibitor, and two specimens (controls) with Virginia Department of Transportation specification concrete (A-4) were built to study diffusion characteristics of these concretes and to estimate corresponding corrosion initiation times. The methodology used to estimate the corrosion initiation times is based on Fick’s Second Law of Diffusion. It uses laboratory concrete diffusion characteristics and cumulative distribution functions of the field surface concentration and diffusion coefficient values. The calculations are performed for various cover depths, and a set of curves is provided for each concrete type and for low, mean, and high values of surface concentration (exposure severity) and diffusion coefficient (concrete quality). The analysis results demonstrate the benefits of using mineral admixtures, especially when combined with a corrosion inhibitor.

Abstract:
The life of the concrete is strongly influenced by durability parameters. The permeability is one of the main characteristics influencing the durability of concrete. The concrete is more permeable due to the ingress of water, oxygen, chloride, sulphate, and other potential deleterious substances. The durability of concrete is mainly affected by pore structure system of concrete and addingthe supplementary cementitious materials (SCM), such as fly ash, slag cement, and silica fume can be decrease permeability. Crystalline technology enhances the strength of concrete by filling the poresand micro-cracks with non-dissolvable substances. To study the efficiency of crystalline formation in concrete in terms of more permeable should be guaranteed through a specific technique.The effectiveness of crystalline waterproofing system with partial replacement cement by GGBS is studiedin terms of strength and durability. The performance of the two different types of crystalline waterproofing integral admixtures has been studied for compressive strength, Split tensile strength, workability, water permeability, Rapid chloride permeability test and porosity in this paper.The early strength increased in GGBS with crystalline admixture concretes compare to the control concrete. No significant strength reduction is observed in GGBS concretes with crystalline admixture when replaced with 20% and 40% of cement than control concrete.

Abstract:
A patent-pending StormPav green pavement is introduced here as a form of permeable road, in which the system employed precast concrete pieces as modular units. The pavement layer consists of hexagonal plates with each a service inlet to drain water. This study is exploring the water draining capability or technically surface permeation of these service inlets. Virtual and physical modelling are performed to investigate the service inlets as multiple orifices to permeate surface water of the said permeable road. Both modelling efforts have deduced that the permeable road has 18,000 – 24,000 mm/hr of permeation rate when subjected to a 5-minute red-alert storm (>60mm/hr of intensity). It implies that StormPav green pavement has superior surface permeation against the forming of water ponding and flash flood on roads.

Abstract:
El presente estudio se sitúa dentro de una línea que profundiza en los componentes culturales de la familia, poniendo de relieve la estrecha conexión entre el parentesco, los valores y hábitos culturales y la organización social. En concreto, en una ciudad mediterránea de la Monarquía Hispánica (siglos XV-XVIII), Murcia, se hizo del parentesco de linaje un valor de rango distinguido y prestigioso, reservado casi exclusivamente a las familias principales. Para éstas fue un importante capital, de origen bajomedieval, construido a partir de brillantes acciones guerreras; y más tarde, conforme se afianzaba el Estado Moderno, formado a través del servicio al monarca. Y fue importante, sobre todo, por su utilidad social: era un requisito pertinente para acceder a la minoría de los selectos y a los beneficios que proporcionaba su hegemonía. Socialmente la perpetuación de tal situación quedó fuertemente ligada a la del propio linaje. Bien es verdad que éste se podía ver interrumpido por cuestiones negativas como los accidentes biológicos, las tendencias dispersantes de algunos integrantes del parentesco, la traición o la falta de fidelidad a las instituciones de poder superiores y a sus disposiciones, etc. Ahora bien, lo más lógico fueron estrategias positivas de reproducción, y para tal fin entendieron el parentesco como algo más permeable que los estrictos lazos de sangre; prefirieron limitar sus relaciones a un círculo social estrecho, de corte endogámico y homogámico; se insertaron dentro de redes de poder; y manifestaron y activaron un amplio conjunto de símbolos (solar, sangre, emblemas y lemas, capellanías, mayorazgos, sitiales, oficios representativos, escudos de armas....) adecuados a su rango.

Abstract:
El Perú presenta diversas eventualidades como las lluvias, que retrasan distintas actividades que promueven el crecimiento económico del país. Las zonas urbanas necesitan una mejora continua del entorno con mejores infraestructuras para promover el crecimiento y reducir los accidentes. En la actualidad, se necesita fomentar por el medio local soluciones innovadoras para la evacuación de altas precipitaciones. El concreto permeable es un tipo de concreto cuya tecnología permite que el agua discurra a través de su estructura por la alta porosidad que posee a diferencia del concreto tradicional. Es fabricado de agregado grueso y material cementante, con un bajo porcentaje de finos de hasta el 10%. Esta investigación consiste en proponer un diseño de mezcla de concreto permeable de f’c=175kg/cm² aplicado en veredas que satisfaga distintos requerimientos establecidos por las normas CE010 de Pavimentos Urbanos, ACI 211.3R, ACI 522R-10 y los propios de la zona de aplicación. Para ello se realizó una batería de 12 diseños de mezcla con relaciones a/c 0.30, 0.35 y 0.38; agregados de HUSO 7 y 67; cementos portland tipo 1 Sol y Quisqueya; y aditivo Z fluidizante SR. Se realizaron ensayos en estado fresco: Slump, peso volumétrico y contenido de vacíos; y en estado endurecido: Resistencia a la compresión y flexión, y permeabilidad. Finalmente se realizó un prototipo con el diseño que presentó mejores características con el propósito de validar la investigación y se realizo un comparativo entre las veredas de concreto permeable y tradicional.
Peru presents various eventualities such as rainfall, which delay different activities that promote the country's economic growth. Urban areas need continuous improvement of the environment with better infrastructure to promote growth and reduce accidents. At present, innovative solutions for the evacuation of high rainfall need to be promoted through the local environment. Permeable concrete is a type of concrete whose technology allows water to flow through its structure due to the high porosity it possesses, unlike traditional concrete. It is made of coarse aggregate and cementitious material, with a low percentage of fines of up to 10%. This research consists in proposing a permeable concrete mix design of f'c = 175kg / cm² applied in sidewalks that satisfies different requirements established by the CE010 standards of Urban Pavements, ACI 211.3R, ACI 522R-10 and those of the area of application. For this, a battery of 12 mixing designs with a / c ratios of 0.30, 0.35 and 0.38; aggregates of HUSO 7 and 67; portland cements type 1 Sol and Quisqueya; and fluidizing Z additive SR. Fresh tests were performed: Slump, volumetric weight and void content; and in a hardened state: resistance to compression and flexion, and permeability. Finally, a prototype was made with the design that presented better characteristics with the purpose of validating the research and a comparison was made between the permeable and traditional concrete sidewalks.

La presente tesis consiste en presentar una propuesta sostenible que ayude en el control y almacenamiento del agua de lluvia para evitar inundaciones y daños producidos en los estacionamientos de los hospitales en la ciudad de Arequipa. Se evaluaron dieciocho diseños de mezclas, nueve realizados con agregado grueso Huso 7 y los otros nueve con Huso 67. Para los diferentes diseños se cambió el porcentaje de agregado fino, la relación agua/cemento y la dosis de los aditivos. Por cada diseño de mezcla se elaboraron nueve probetas destinadas al ensayo de resistencia a la compresión, tres por cada edad, ensayadas a los 7, 14 y 28 días; se utilizaron 2 vigas de 6”x6”x20” para determinar el Módulo de Rotura y 2 probetas de 4”x8” para hallar la tasa de permeabilidad, para lo cual se necesitó realizar una réplica del permeabilímetro expuesto en el ACI 522. Los resultados de todos los ensayos serán presentados y comparados entre sí para determinar el grado de influencia de los mismos. Además, también se realizará un análisis costo beneficio por metro cuadrado para determinar qué tanto varía el costo del concreto permeable en comparación con el concreto convencional. Finalmente, se realizará un análisis cuantitativo entre los dieciocho diseños de mezcla y el concreto convencional. Para así determinar cuál es la mezcla óptima que cumpla con los requisitos necesarios para ser implementado en los estacionamientos de los hospitales en Arequipa y pueda competir en el mercado con el concreto convencional.
The present thesis consists of presenting a sustainable proposal that helps in the control and storage of rainwater to avoid floods and damages produced in the parking lots of hospitals in the city of Arequipa. Eighteen mix designs were evaluated, nine made with coarse aggregate Spindle 7 and the other nine with Spindle 67. For the different designs, the percentage of fine aggregate, the water / cement ratio and the dose of the additives were changed. For each mix design, nine specimens were prepared for the compression resistance test, three for each age, tested at 7, 14 and 28 days; 2 beams of 6 ”x6” x20 ”were used to determine the Modulus of Break and 2 specimens of 4” x8 ”to find the permeability rate, for which it was necessary to make a replica of the permeabilimeter exposed in the ACI 522. The results of all the tests will be presented and compared with each other to determine the degree of influence between them. In addition, a cost benefit analysis per square meter will also be performed to determine how much the cost of pervious concrete varies compared to conventional concrete. Finally, a quantitative analysis will be performed between the eighteen mix designs and conventional concrete. In order to determine which is the optimal mix that meets the necessary requirements to be implemented in hospital´s parking lots in Arequipa and can compete in the market with conventional concrete.

Abstract:
Nos dias atuais todas as grandes metrópoles enfrentam inúmeros problemas devidos, muitas vezes, a um deficiente planejamento urbano onde se inclui certo descaso com a proteção do meio ambiente. Um aspecto importante é a desordenada expansão urbana, que têm crescido com o passar dos anos. Este fator poderá comprometer a saúde do meio ambiente. Mencionase também o descaso da população com os recursos hídricos, o solo e a vegetação. Dentro deste enfoque, o tradicional sistema de drenagem, baseado em um rápido afastamento do excesso pluvial, contribui para um aumento nos volumes escoados e vazões de pico e uma redução no tempo do escoamento, fazendo com que os hidrogramas de cheia sejam mais críticos, aumentando-se, assim, a freqüência e a gravidade das inundações. Pesquisas apontam uma grande relação entre os índices de permeabilidade com a densidade habitacional. Essencialmente, o concreto permeável é um pavimento de concreto estrutural, com um grande volume de vazios interconectados (15 a 35%). Como o concreto convencional, é feito de uma mistura de cimento, agregados graúdos e água. Contendo pouca ou nenhuma areia, resulta em uma estrutura celular porosa que permite que a água passe facilmente. Em países desenvolvidos houve um aumento de interesse na sua utilização, para um controle mais efetivo das águas do escoamento superficial. Dependendo das normas locais e das características do meio, o pavimento e sua sub-base podem ter capacidade suficiente de infiltração para eliminar a necessidade de outras obras de drenagem. O objetivo deste trabalho consistiu no desenvolvimento de um concreto permeável para utilização em grandes áreas. Pretendeu-se englobar um entendimento de suas propriedades e um desenvolvimento de diversos traços. Para tanto se formularam e caracterizaram diferentes traços de concreto permeável, estudando as dificuldades para fabricação em campo e analisando as possibilidades de aplicação e as possíveis repercussões na drenagem. Os resultados de resistência à compressão foram, em média, de 8 MPa e os de permeabilidade, mais variados, ficaram numa faixa de 100 a 1000l/min./m2. Para um uso eficaz desse concreto, deve-se avaliar a capacidade de percolação do solo abaixo do pavimento.
Nowadays, all major cities often face many problems due to a poor town planning, which also includes certain disregard towards protecting the environment. Another important aspect is the disorderly urban expansion, which has grown over the years. This factor may compromise the health of the environment. It can also be mentioned the population’s neglect with water, soil and vegetation. Within this approach, the traditional drainage system, based on a rapid removal of excess rain, contributes to an increase in drained volume and peak flow and a reduction in the time of the flow, causing the flood hydrographs to be more critical, increasing, thus, the frequency and severity of floods. Research indicates a strong relationship between rates of permeability with the density of housing. Essentially, the concrete is a permeable structural concrete pavement with a large volume of interconnected voids (15 to 35%). As conventional concrete, it is made from a mixture of cement, coarse aggregates and water. Containing little or no sand, it results in a sporous cell structure that allows water to pass easily. In developed countries there has been an increased interest in its use, in order to obtain a more effective control of the runoffs. Depending on local rules and characteristics of the environment, pavement and its sub-base may have enough capacity to eliminate infiltration which excludes the need for other drainage works. The aim of this paper is the development of a permeable concrete to be used in large areas. It aims to encompass an understanding of its properties and development of its various traits. Hence, have been formulated and characterized different traces of permeable concrete, studying the difficulties of manufacturing it in the field and analyzing its possible applications and its possible impact on drainage. The results of compressive strength were on average of 8 MPa and the permeability, more varied, were in the range of 100 to 1000l/min./m2. For an efficient use of this concrete, we should evaluate the ability of soil percolation below the pavement.

Abstract:
La tesis trata de encontrar una alternativa de solución que ayude al control de las aguas pluviales provenientes de precipitaciones anormales debido a una alteración del clima por la ocurrencia de El Niño - Oscilación Sur en la costa noroeste del Perú. Para ello se evalúa implementar el concreto permeable en vías locales y pavimentos especiales de dicha región. Se combinan aspectos tanto hidráulicos como estructurales, así el pavimento debe ser capaz de drenar cierto volumen de agua y proporcionar resistencia estructural adecuada para el tipo de vía a evaluar. Se analiza la capacidad estructural del concreto permeable, midiendo su resistencia a la compresión y a tracción por flexión. Luego, se comparan los resultados con los requerimientos para la capa de rodadura en vías locales y pavimentos especiales de acuerdo a la CE. 010 Pavimentos Urbanos y a las normas ACI. Para que pueda ser utilizado en sistemas de drenaje pluvial, se identificaron las precipitaciones ocurridas durante El Niño - Oscilación Sur durante los años de 1997-1998 en la costa noroeste del Perú. De esta base de datos, se estudiaron las máximas precipitaciones registradas y se establecieron requisitos de permeabilidad. El desempeño estructural e hidráulico del concreto permeable es cuantificado a través de sus propiedades de resistencia y permeabilidad, respectivamente, de acuerdo al ACI 522R-10 y a las pruebas de ensayo de ASTM. Parar ello, se evaluaron quince mezclas de concreto permeable. De cada mezcla se elaboraron ocho probetas de 6” x 12” para el ensayo de resistencia a la compresión (ASTM C39 y ACI 522R-10); tres probetas de 4” x 8” para el ensayo de permeabilidad (ACI 522R-10), y dos vigas para el ensayo de resistencia a la tracción por flexión (ASTM C 78). En el diseño de mezclas se han tomado como variables el porcentaje de vacíos, la relación arena/grava y el tipo de agregado grueso (forma y tamaño máximo). El ensayo de permeabilidad se realizó de acuerdo a lo sugerido por el ACI 522R-10 para lo cual se realizó la construcción de un permeámetro de carga variable y se obtuvo el coeficiente de permeabilidad por la Ley de Darcy.

Las variables independientes son el agregado fino y el aditivo SikaCem Plastificante. Por otra parte, las variables dependientes son las propiedades mecánicas e hidráulicas del concreto permeable; medidas a través de sus indicadores como son: el asentamiento, temperatura, densidad, contenido de vacíos, resistencia a la compresión, resistencia a la flexión, resistencia a la abrasión y permeabilidad. Por ello, la investigación es experimental y tiene una muestra de 90 probetas para el ensayo a compresión, 30 probetas para el ensayo de permeabilidad, 60 probetas para el ensayo de abrasión y 60 vigas para el ensayo de flexión. Se concluyó que utilizando 20% de agregado fino, agregado de 3/4” y una relación agua/cemento de 0.30 se obtienen las propiedades necesarias en el concreto permeable para ser empleado en veredas o ciclovías con una capacidad de drenaje de 22.4 Lt/m2/s, resistencia a la compresión de 189.2 kg/cm2 y pérdida de masa por abrasión de 32.7%. Adicionando 500 mL de aditivo SikaCem Plastificante por bolsa de cemento al diseño anterior se mejoran las propiedades del concreto permeable obteniendo una capacidad de drenaje de 19.9 Lt/m2/s, resistencia a la compresión de 213.7 kg/cm2 y pérdida de masa por abrasión 28.8%.

Abstract:
El crecimiento acelerado de las urbes y el uso de materiales impermeables han impactado negativamente en el ciclo hidrológico. Las fuertes precipitaciones durante la época de lluvias generan el colapso de redes de alcantarillado en ciudades con la infraestructura inadecuada. Dicha escorrentía acelera el deterioro de los pavimentos, además de la incomodidad y peligro debido al hidroplaneo que impacta en los peatones. El concreto permeable es un material adecuado para mitigar estos problemas debido a su propiedad de discurrir el agua entre sus poros, además de ser ecológico y sostenible. Ya que su resistencia es menor a la del concreto convencional, su uso es limitado en pavimentos rígidos, por ello la incorporación de fibras le proporcionaría un mejor desempeño mecánico. Mediante un análisis cualitativo de diversos factores, se determinó que las fibras de basalto optimizarían el comportamiento del concreto permeable para su aplicación en pavimentos urbanos. Además, se tomó en consideración que el suelo del área de estudio es de grava y la infiltración requerida es de 192.22mm/h. El diseño de mezcla de referencia corresponde a similares características con el área de estudio y finalmente las cantidades requeridas en el diseño de esta investigación son 443.12 kg/m3 de cemento, 130.43 l/m3 de agua, 135.16 kg/m3 de agregado fino, 1312.04 kg/m3 de agregado grueso, 3.99 kg/m3 de aditivo superplastificante; añadido a fibras de basalto en porcentajes de 0%, 0.1%, 0.2% y 0.3% respecto del diseño de mezcla.
The accelerated growth of cities and the use of waterproof materials have negatively impacted the hydrological cycle. Heavy rainfall during the rainy season leads to the collapse of sewerage networks in cities with inadequate infrastructure. Such runoff accelerates the deterioration of pavements, in addition to the discomfort and danger due to hydroplaning that impacts pedestrians. Pervious concrete is a suitable material to mitigate these problems due to its property of running water through its pores, in addition to being ecological and sustainable. Since its resistance is less than that of conventional concrete, its use is limited in rigid pavements, therefore the incorporation of fibers would provide better mechanical performance. Through a qualitative analysis of various factors, it was determined that basalt fibers would optimize the behavior of pervious concrete for application in urban pavements. In addition, it was taken into consideration that the soil of the study area is gravel and the required infiltration is 192.22 mm/h. The reference mix design corresponds to similar characteristics with the study area and finally the quantities required in the design of this research are 443.12 kg/m3 of cement, 130.43 l / m3 of water, 135.16 kg/m3 of fine aggregate, 1312.04 kg/m3 of coarse aggregate, 3.99 kg/m3 of superplasticizer additive; added to basalt fibers in percentages of 0%, 0.1%, 0.2% and 0.3% with respect to the mix design.

Abstract:
El concreto permeable es un concreto especial, el cual permite el paso del agua a través de su estructura gracias al alto porcentaje de vacíos que posee a diferencia del concreto tradicional. Esta cualidad del concreto permeable permite acabar con la falta de permeabilidad en las estructuras tradicionales de concreto evitando las fallas estructurales debido al encharcamiento y escurrimiento del agua. En esta investigación se realizó el diseño de mezcla del concreto permeable con una resistencia de 210 kg/cm2, aplicando el método ACI 522.R para poder aplicarlo como una alternativa de carpeta de rodadura en pavimentos. Para ello se realizaron diferentes diseños de mezcla en laboratorio hasta encontrar el diseño óptimo para obtener una resistencia a la compresión de 210 kg/cm2, el diseño de mezcla elegido contaba con las siguientes características: relación agua/cemento de 0.38, porcentaje de vacíos de 13%, 1.5% de aditivo Superplastificante y 7% de arena. Para validar la investigación se realizó la construcción de un prototipo con el diseño elaborado en laboratorio con un área de 2.00 m2 (1.00m x 2.00m). Al concreto en estado fresco se le analizaron sus características de consistencia, densidad y contenido de vacíos; en el estado endurecido se realizaron los ensayos de compresión, permeabilidad y flexión, además de aplicarle una prueba de carga. Los resultados indicaron que el diseño de mezcla usado en el prototipo con resistencia a la compresión de 261.58 kg/cm2 y permeabilidad de 0.01744 m/s puede usarse como alternativa de superficie de rodadura para un pavimento.
Pervious concrete is a special type of concrete which allows the passage of water through its structure due to its high percentage of voids unlike traditional concrete. This quality of pervious concrete allows to end the lack of permeability in traditional concrete structures thus preventing structural failures due to flooding and water runoff. This research will seek to find a mix design for pervious concrete to apply it as an alternative road surface for pavements. To verify the above, different mix designs were performed in laboratory to find the design that give us a compressive strength of 210 kg/cm2, the chosen design had the following features: water - cement ratio of 0.38, 13% air content, 1.5% additive superplasticizer and 7% of sand. To validate the research, a prototype was built with the chosen mix design, this prototype had an area of 2 m2 (1m x 2m). The fresh concrete was analyzed for its consistency, density, and void percentage; the hardened concrete was analyzed for its compressive strength, permeability and flexural strength, finally the prototype was load tested. The results indicated that the mix design used in the prototype with compressive strength of 261.58 kg/cm2 and a permeability of 0.01744 m/s can be used as an alternative rolling surface for pavements.

Abstract:
El fenómeno El Niño provoca intensas precipitaciones pluviales que se acumulan y discurren por la superficie, transportando importantes caudales de agua que se incrementan con el desplazamiento debido a la carencia de un pavimento permeable como sucede en la ciudad de Tumbes. Esta deficiencia produce daños en los sistemas de abastecimiento de agua, alcantarillado y aguas pluviales que, debido a la cantidad de basura y lodo que transportan los azolvamientos severos, afectan a las infraestructuras hidráulicas, medio ambiente y calidad de vida de la población. Una propuesta de solución es utilizar un sistema de drenaje urbano sostenible que permita complementar el sistema único de saneamiento diseñado para las aguas servidas, residuales y pluviales, existente en la gran mayoría de ciudades. Esta solución consiste en el diseño de un pavimento permeable porque permite alcanzar un volumen de captación de agua de 81-730 l/min/m2 debido al contenido de vacíos de 13 a 25%. Esta característica física es importante para garantizar la infiltración de grandes volúmenes de agua mediante sus poros para luego transmitir a estratos subyacentes; reducir el flujo del calor al conductor; y mitigar la isla de calor urbano en las ciudades. La presente investigación tiene como objetivo evaluar el desempeño del concreto permeable mediante 5 diseños de mezcla para estudiar la resistencia a la compresión, a la flexión y permeabilidad; la comparación de la escorrentía superficial pluvial de un pavimento de concreto permeable con un pavimento de concreto convencional mediante el software SWMM 5.1; y la comparación respecto al costo.
The El Niño phenomenon causes intense rainfall that accumulates and runs over the surface, transporting significant volumes of water that increase with displacement due to the lack of a permeable pavement, as happens in the city of Tumbes. This deficiency causes damage to the water supply, sewerage, and rainwater systems that, due to the amount of garbage and mud transported by severe silts, affect the hydraulic infrastructures, environment, and quality of life of the population. A proposed solution is to use a sustainable urban drainage system that allows complementing the unique sanitation system designed for sewage, waste, and storm water, existing in most cities. This solution consists of the design of a permeable pavement because it allows reaching a water collection volume of 81-730 l/min/m2 due to the void content of 13 to 25%. This physical characteristic is important to guarantee the infiltration of large volumes of water through its pores and then transmit to underlying strata; reduce heat flow to the conductor; and mitigate the urban heat island in cities. The objective of this research is to evaluate the performance of permeable concrete through 5 mix designs to study the resistance to compression, bending and permeability; the comparison of the surface rain runoff of a permeable concrete pavement with a conventional concrete pavement using SWMM 5.1 software; and the cost comparison.

Abstract:
How do the various phenomena that we encounter in the world—from concrete historical events to mediated representations, as may be found in books and films and other “second-hand” sources—permeate us and become inscribed in memory? Where does all of this information “go” after we have encountered it, and how is it metabolized? Some dimensions of such experiences no doubt dissipate or disappear, whereas others seep into our psyches often in ways unbeknownst to us, thus becoming part of what is called the narrative unconscious. The narrative unconscious thus refers to those culturally rooted aspects of our histories that have yet to become an explicit part of our life stories, and it includes not only those events and encounters that occur in our lifetime but also those that precede us. By exploring some significant sites of the narrative unconscious, we may more readily discern the deep historical roots of our own psychological formation.

Abstract:
Photocatalyst such as Titanium Dioxide (TiO2) has been recently introduced as a nanoparticle into cementitious permeable pavements. Combining photocatalytic compounds within concrete permeable pavements can aid with depollution of several contaminants found in urban water streams and air impurities. This paper presents research carried out at the University of Greenwich, UK using photocatalytic concrete with varying percentages of TiO2 (0 %, 1% and 5%) to assess the levels depollution which can be achieved. Concrete samples were testing against the degradation of 2, 4-Dichlorophenoxyacetic Acid, a harmful chemical found in herbicides. This advanced oxidation process can aid in the reduction of urban pollution from an air and water perspective, improving sustainability for urban cities. Self-cleaning benefits of photocatalytic concrete permeable pavements can be used to keep urban infrastructure cleaner and more aesthetically pleasing. Experimental tests were carried out on the characterisation of inorganics through X-Ray diffraction and Fourier Transform Infrared Spectroscopy to ensure that the structures of the concrete samples were not altered by addition of the nanoparticles (photocatalyst). Experimental results were compared to that found in previous literature and confirmed that the addition of 5% TiO2 did not affect the structure of the concrete samples and can be a viable option used in urban infrastructure such as permeable pavements.

Abstract:
Abstract. Our towns are increasingly protected by buildings and water paved pavements. Moreover, the city's climate is far from normal. Rainwater is not filtered underground due to the absence of the permeability of the common concrete pavement to water and air permeability. In addition, the exchange of heat and humidity with air is difficult for the soil, and it's not possible to change the temperature and relative humidity of the Earth's surface in urban areas. At the same time, the safety from both car and foot passenger traffic is limited by a plash on the road on a rainy day. Since the 1980s, work on permeable asphalt pavements has started in developed countries like the US and Japan. For roadway applications, permeable concrete is also widely used as a surface course in Europe and Japan Improving skid resistance and reducing noise from traffic. Only about 20 – 30 MPa can the material reach's compressive intensity. Due to their low strength, such materials cannot be used as pavement. Only frames, walking routes, parking garages, and park trails can be used with permeable concrete. Utilizing specified analyses, small materials, admixtures, organic intensifiers and changing the ratio, strength and abrasion resistance of the concrete mix, the porous concrete may be greatly enhanced.
