Abstract:

Lego technology is one of the modern construction solutions providing cost reduction, increasing architectural expressiveness and the pace of work. This is the development of groove-ridge positioning systems and connection of small-piece wall elements. Currently, the technology of Lego blocks is implemented on various types of building materials: ceramic and hyper-pressed non-fired bricks, blocks from various types of lightweight concrete, which have not found wide practical application due to an obvious shift in the balance of properties either towards aesthetics – brick, or thermal insulatio

Abstract:

The possibilities of utilisation of ceramic powder as supplementary cementitious material are the matter of the presented study. The finely ground ceramic powder originates from the grinding process of thermal insulating brick blocks and shows pozzolanic properties. For the determination of its influence on concrete properties, five mixtures with different percentages of cement replaced by ceramics are designed. The bulk density as well as matrix density are found to decrease with the increasing dosage of waste ceramic material, while the open porosity increases. The compressive strength exhib

Abstract:

The modern concepts of civil construction for building with a maximum of 5 stores rely on structural blocks to support part of the load. These are normally hollow parallelepiped pieces made of concrete or fired ceramic. In Brazil, the abundance and easy to mine natural clay deposits favor the use of structural blocks fabricated of fired clay ceramics. Moreover, the available wood from reforestation, as fuel for the ceramic furnaces has the advantages of a less expensive and environmentally correct source of energy. Since the main property of a structural block is its compressive strength, spec

Nowadays, many companies depend on good communication between their technologies and Wi-Fi signal, which are part of the X-waves frequencies. Communication may suffer interference due to wave propagation’s difficulty, mainly depending on the number of walls and where the building is located. Therefore, buildings should be adapted to avoid this interference in order to minimize signal losses. Interference in wave propagation depends not only on walls but also on their structure. The studies of building construction and wave propagation may be complementary since the structure and organization m

One can find opinions that thick thermal insulation creates a “thermos effect” and significantly deteriorates the comfort conditions during the summer.

Abstract:

The aim of this research was to investigate how customers of a technological control laboratory of civil construction materials perceive the quality of the services delivered by the laboratory, specifically, what concerns the service of ceramic brick and concrete blocks breaking. The SERVQUAL scale was used as reference for the application of a survey and, by means of an Exploratory Factor Analyses, the dimensions and attributes that comprehend this service were evaluated. As a result, 20 attributes grouped in three dimensions Responsiveness, Assurance and Reliability) were found, what has res

Abstract:

Paver blocks are used in many areas like street road and other construction places. Due to rapid infrastructure development the use of cement is increasing. Cement emits large amount of carbon dioxide (CO2) and this leads to global warming. Today researches on waste management lead to an eco-friendly product called geopolymer mortar and concrete. To support the development of pavement construction in the civil engineering industry, a new approach to predicting the performance of the geopolymer paver block (GPB) has been proposed. A huge quantity of ceramic waste is generated during processing,

Abstract. The new transdisciplinary science of geonics (geomimetics) is the theoretical basis for designing construction composites from fragments of destroyed buildings and structures. Technogenic and natural anomalies, military conflicts on planet Earth lead to destruction of cities. Utilization of fragments of destroyed buildings and structures for the production of building materials is relevant. The classification and scheme of using fragments of destroyed buildings and structures to obtain crushed stone, sand, solutions and concretes based on them is proposed. The densest packaging

Resumen Se analizan las características térmicas y de resistencias mecánicas de materiales y elementos constructivos elaborados con suelos naturales estabilizados. La metodología parte de la recopilación bibliográfica de fuentes primarias, secundarias e información de ensayos propios, sobre la densidad, la conductividad térmica y las resistencias a la compresión, a la flexión y al corte correspondientes al adobe, los bloques de tierra comprimida (BTC), la tapia y la quincha, según diferentes autores. Además, se consideraron los valores establecidos por normas argentinas IRAM referidas al
