Full textAbstract:
This study investigated the impact of using cow dung ash (CDA) as a partial replacement for ordinary Portland cement (OPC) in mortar. Mortar mixes are prepared by replacing OPC with CDA at varying levels: 5%, 10%, 15%, 20%, 25%, and 30%. The chemical composition of CDA shows that it is composed primarily of SiO2, Al2O3, and Fe2O3, with a significant amount of loss of ignition. The workability, hardened properties, and microstructure of CDA-containing mortars are also analyzed. The increasing CDA content in mortar reduces workability and, beyond 5%, it causes high water absorption due to CDA’s porous nature and unremoved organic compounds. This impacts the density and compressive strength of the hardened mortar as well as compromising its homogeneous characteristics. When using 5% CDA, the bulk density and compressive strength of the mortar are comparable to those of the control mixes. Nonetheless, as the proportion of CDA increases, both the bulk density and compressive strength of the mortar diminish. The thermal stability of mortar mixes with 10%, 20%, and 30% CDA is unaffected at temperatures between 500 °C and 600 °C. The Fourier-transform infrared spectroscopy (FTIR) analysis reveals the presence of unreacted particles and wide stretched C–S–H gels in the mortar samples. In general, the results suggest that CDA can be utilized as a substitute for OPC at a ratio of up to 10% in the manufacturing of mortar and can serve as a feasible alternative cementitious material.

Cement is the main binder in the production of concrete for construction activities. Unfortunately, the continuous use of cement results in severe environmental and energy concerns. An established way of reducing carbon footprints and the energy demands associated with cement production is the use of supplementary cementitious material (SCMs). Most supplementary cementitious materials are processed from agro-wastes and bye-products like cow dung. Although cow dung has been utilized as manure, for heating and so on, its use is yet to match the level of production. In this study, the authors propose to investigate the strength performance of cow dung ash as SCMs. Cow dung ash is the product of controlled burning of dried cow dung. Concrete beams and cubes containing 0% to 30% cow dung ash as cement replacement were cured by complete immersion in water for 7,14,28,60 and 90 days. Compressive and flexural strengths decreased as CDA increases; and increased with curing age. Concrete made with 5%, 10%, and 15% CDA and cured for at least 60 days achieved the 28days target compressive strength of 20N/mm<sup>2</sup>. The strength test results were analysed by analysis of variance (ANOVA) and regression analysis. Proposed regression models showed a strong relationship between the strengths, CDA content and curing age. The proposed models were examined and found to be permissible

Abstract: Rice Husk Ash (RHA) and Cow Dung Ash (CDA) are agriculturally based pozzolanic materials, these materials are available in huge quantities. This final year project report highlights and presents the results of the study on the use of Cow Dung Ash and Rice Husk Ash as partial replacement of cement in concrete. The experiments were conducted to study the impacts of adding Cow Dung Ash and Rice Husk Ash in several percentages by weight (0%, 5%, 10%, 15%, and 20%) of cement and cure for periods of 28 days before testing for compression strength. The consistency, workability, sieve analysis of aggregates were also tested in this research study. The Compressive test results are 37.75 N/mm2, 31.25 N/mm2, 31.25N/mm2 and 25.25 N/mm2 for 0%, 5%, 10% and 15% replacement of cement with Cow Dung Ash and Rice Husk Ash respectively at 28days. The Workability results gives 45mm, 49mm, 56mm, 68mm and 75mm respectively for 0%,5%, 10%, 15%, and 20% replacement of cement with Cow Dung Ash and Rice Husk Ash. The consistency test results are 0.29, 0.32, 0.36, 0.41 and 0.43 for 0%, 5%, 10%, 15% and 20% replacement of cement with Cow Dung Ash and Rice Husk Ash respectively. The bulk density results are 2452.53 kg/m3, 2370.8 kg/m3, 2380.0 kg/m3 and 2348.5 kg/m3 for 0%, 5%, 10% and 15% replacement of cement with Cow Dung Ash and Rice Husk Ash respectively. The main highlights, it should be highlighted that the more quantity of water is required to standard consistency as the percentages of Cow Dung Ash and Rice Husk Ash are added. Dung Ash and Rice Husk Ash concrete is recommended for use when a ten percentage (10%) of Cow Dung Ash and rice husk ash are not exceeded

Full textAbstract:
The objective of this paper was to investigate the effects of cow dung ash (CDA) on the chemical and geotechnical properties of lateritic soil for road construction collected Shao-Malete Road in Kwara State, Nigeria. Cow dung ash (CDA) was used in stabilizing lateritic soil at ratios 0, 2, 4, 6, 8 and 10% of disturbed soil sample (fine - grained i.e. silt-clay material). The soil samples were subjected to laboratory tests such as Specific gravity, particle size distribution, Atterberg limits, compaction, California bearing ratio, unconfined compressive strength, Triaxial shear strength in accordance with British Standards (BS 1377: 1990 and BS 1924: 1990). Optimum addition of cow dung ash was achieved at 6%. The investigation on the soil samples revealed an increased in strength tests performed on the selected soil samples and a gradual decrease in the results of optimum moisture content. Optimum of CDA was recorded at 6% which is best suitable for silt-clay soil. In conclusion, materials from selected locations meet the requirements for sub-base and base courses when stabilized with optimum cow dung ash. If the research work is utilized for road and building construction, it will surely cut down expenses and environmental risks brought about by agricultural waste.

Full textAbstract:
Experimental investigations were carried out to study the cow dung ash on the strength of concrete. Cement was partially replaced with four percentages (5%, 10%, 15%, 20%) of cow dung ash by weight in M20 grade concrete mix. Test performed on the concrete mix are compressive strength, splitting tensile strength and workability. The compressive strengths of the concrete specimens were determined at 7 and 28 days respectively. The tests were performed on the moulds of size (150mm x150mm x150mm).Workability test is done using compaction factor apparatus. Workability Test shows that workability of concrete decreases as percentage of cow dung ash increases in concrete mix. When compared to normal concrete the concrete containing 10% of CDA has 17% increase in compressive strength and 15% increase in Tensile Strength. The Compressive Strength and Tensile strength tends to decrease after 10%. Thus 10% replacement of cement by CDA gives satisfactory result.

This paper presents the investigation made on cow dung ash (CDA) alone and a combination of CDA and lime for stabilizing expansive black clay soil with high plasticity used as a subgrade for road pavement. The study was mainly conducted to assess the performance of expansive black clay soil when stabilized with CDA and lime, and its suitability to solve the issue of structural damage identified on the road. The chemical compositions of lime, CDA, and natural unstabilized subgrade soil (control) were determined using X-ray fluorescence. The plastic limit (PL), plasticity index (PI), liquid limit (LL), linear shrinkage (LS), maximum dry density (MDD), optimum moisture content (OMC), free swell index (FSI), California bearing ratio (CBR) and unconfined compressive strength (UCS) of the control soil, the control soil mixed with varying quantities (0%, 6%, 10%, 14%, 20%, and 25% by dry weight of the soil) of CDA, and the control soil mixed with varying CDA-lime combinations consisting of mixtures of 5% lime with 10%,15% and 20% of CDA were determined experimentally. The experimental outcomes showed that the soil stabilized with the CDA-lime combination is synergistic, improves the CBR and UCS and lowers the PI, and swelling potential of the soil more than the soil stabilization with CDA alone.

Metal matrix composites (MMCs) provide superior properties than other materials. Because of these advantages, MMCs are widely employed in a variety of engineering applications. Metal has better properties in general, and when reinforced with certain particles, exceptional properties can be obtained. This study focuses on environmentally beneficial agricultural waste, cow dung ash, and tungsten carbide reinforced stir cast aluminium hybrid metal matrix composites. Hardness has been investigated and evaluated as a mechanical property. The hardness of hybrid composites has increased due to the addition of stiffer and stronger reinforcement in the matrix material. The matrix alloy's ability to reinforce with WC and cow dung ash can significantly increase the hardness of an aluminium hybrid composite.

Full textAbstract:
This study aims to determine whether it is feasible to replace conventional materials used in manufacturing concrete with waste materials, namely cow dung ash and corn stalk ash. This study proposes to assess the possibility of using these agricultural by-products to improve the sustainability of concrete while simultaneously tackling the environmental issues related to the manufacture of conventional concrete. The research aims to assess the mechanical qualities, optimize the mix proportions, and examine the ecological implications of using these substitute materials. This research aims to mitigate environmental challenges like carbon dioxide emissions, resource depletion, and the accumulation of agricultural waste by combining agricultural waste and lowering dependency on traditional cement. The study investigates the use of cow dung ash (CDA) and corn stalk ash (CSA) as alternatives for conventional Portland cement (OPC) in mortar mixes at varying quantities, ranging from 5% to 25% CDA and 2.5% to 10% CSA. Chemical composition reveals that CDA and CSA predominantly comprise O, Mg, Al, Si, P, K, and Ca. The workability, hardened characteristics, and microstructure of CDA and CSA were assessed. Increasing CDA and CSA percentages reduced mortar workability; nevertheless, replacing 8% to 10% CDA and 7.5% CSA maintained compressive, tensile, and flexural strengths comparable to control mixes. However, more significant CDA and CSA proportions resulted in lower mortar strength. For example, 10% CDA-enriched mortar had a compressive strength of 31.77 N/mm2, a tensile strength of 3.42 N/mm2, and a flexural strength of 3.61 N/mm2, whereas 7.5% CSA-enriched mortar had a compressive strength of 28.4 N/mm2, a tensile strength of 3.04 N/mm2, and a flexural strength of 3.7 N/mm2. According to the findings, CDA and CSA can replace OPC by up to 10% and 7.5% in mortar manufacturing, making cementitious material alternatives viable. Doi: 10.28991/CEJ-SP2024-010-02 Full Text: PDF

Full textAbstract:
Adlay (Coix lacryma-jobi L.) is an emerging alternative cereal crop which may benefit from plant tissue culture approaches. In this study, the morphogenic response of mature embryos of adlay to 2,4-dichlorophenoxyacetic acid (2,4-D; 1–3 ppm) and benzylaminopurine (BAP; 1–3 ppm) in Murashige and Skoog (MS) basal medium was screened in vitro. Further, agnihotra ash (AA) and cow dung ash (CDA) were evaluated as unconventional culture media additives. A sterilization procedure was first developed for mature embryos of adlay by varying sodium hypochlorite (NaOCl) concentration and the duration of surface sterilization. NaOCl at 1% (v/v, Chlorox®) using double sterilization (7 min: 8 min) was effective for surface disinfection of dehusked adlay seeds. In terms of plant growth regulators (PGRs), BAP and 2,4-D enhanced shoot growth in lower doses, but primary root growth was inhibited. Retarded shoot and root development were observed even at the lowest 2,4-D concentration and as BAP was increased. Yellow, compact callus was observed surrounding the mesocotyl and white crystalline and loose callus around the radicle region. Both types of calli appeared non-embryogenic and were most frequent at 2 and 3 ppm 2,4-D regardless of BAP concentration and ash additives. As for ash additives, application of 0.01% cow dung ash, 0.01% agnihotra ash and 1% cow dung ash resulted in larger seedlings compared with 1% agnihotra ash in basal media, although these differences were not pronounced in the plant growth regulator (PGR) background. Agnihotra ash and cow dung ash as miscellaneous additives may provide cost savings in plant tissue culture; further work is warranted.

Informe sobre o proxecto para a implantación dunha industria de fibra téxtil a base de celulosa e as súas infraestruturas asociadas. Consello da Cultura Galega, 2024. http://dx.doi.org/10.17075/piiftbcia.2024.
Full textAbstract:
O 4 de marzo o Diario Oficial de Galicia (DOG, núm. 45 de 2024) publicou o anuncio do 20 de febreiro de 2024, da Secretaría Xeral de Industria, polo que se someten a información pública a solicitude de autorización ambiental integrada (AAI), o estudo de impacto ambiental (EIA), a declaración de utilidade pública e o proxecto para a implantación dunha industria de fibra téxtil a base de celulosa e as súas infraestruturas asociadas, promovido por Greenfiber, S.L. e declarado proxecto industrial estratéxico (PIE) polo Acordo do Consello da Xunta de Galicia, do 29 de decembro de 2022, que se vai implantar no concello de Palas de Rei. O artigo 80.4 do Decreto lexislativo 1/2015, do 12 de febreiro, especifica que, «[s]imultaneamente ao trámite de información pública, o órgano responsable da tramitación efectuará a petición de todos os informes ás administracións e aos órganos sectoriais afectados, tanto os exixidos pola normativa reguladora da autorización sectorial como os exixidos para os efectos da tramitación ambiental». Ao Consello da Cultura Galega non lle foi solicitado informe ningún por parte dos poderes públicos da comunidade autónoma galega. O Decreto 162/2008, do 10 de xullo, polo que se aproba o regulamento de organización e funcionamento do Consello da Cultura Galega, establece no seu artigo 1.2 que «[o] Consello da Cultura Galega goza de plena autonomía orgánica e funcional, e actúa con independencia e obxectividade respecto dos poderes da comunidade autónoma e da súa Administración». Establece entre as súas competencias e fins, entre outros, «[a]nalizar cantas cuestións se refiran ao patrimonio cultural de Galicia», «[a]sesorar e consultar os poderes da comunidade autónoma no que xulgue preciso para a defensa e promoción dos valores culturais do pobo galego», ou «[e]levar aos poderes da comunidade autónoma informes e propostas a favor da defensa e promoción dos valores culturais do pobo galego». Igualmente, o Consello da Cultura Galega, segundo establece o artigo 7.1 da Lei 5/2016, do 4 de maio, do patrimonio cultural de Galicia, «é o máximo órgano de asesoramento e consulta dos poderes públicos» da Comunidade Autónoma con relación ao patrimonio. Ao non recibir ningunha solicitude de informe por parte dos poderes públicos sobre as posibles afeccións patrimoniais e ambientais do devandito proxecto, por unha parte, o CCG solicitou á Consellería de Economía e Industria a apertura dun prazo extraordinario para poder elaborar ese informe; e, por outra, o CCG decidiu facer un informe por iniciativa propia que avaliase os potenciais impactos no patrimonio cultural e natural do proxecto industrial estratéxico (PIE) para a implantación dunha industria de fibra téxtil a base de celulosa e as súas infraestruturas asociadas, promovido por Greenfiber, S. L. (proxecto Gama). A resposta da Secretaría Xeral de Industria e Desenvolvemento, asinada o 31/7/2024 e na que se rexeitaba a solicitude do CCG, foi recibida cando este informe estaba rematado e xa fora aprobado pola Comisión Executiva do CCG. O proxecto Gama é, en si mesmo, singular, polo tipo e características do proceso industrial que vai desenvolver, que pode producir impactos relevantes no 6 medio ambiente, no territorio e na sociedade que o habita. A área da comarca da Ulloa na que se pretende implantar a fábrica, e outras veciñas, contan con importantes valores patrimoniais que poden ser afectados polas transformacións que o proxecto vai producir e que incluso se poden estender fóra dos límites do espazo que vai ocupar. Como recolle a Guía práctica para a análise dun sector clave na gobernanza do futuro, editada polo Consello da Cultura Galega (Blanco-Rotea, Nieto Freire e Sánchez- Carretero, 2021)1: A conservación e a xestión dos recursos naturais e do patrimonio cultural é un dos obxectivos a nivel europeo das políticas de desenvolvemento territorial — Estratexia Territorial Europea 1999—. Estas demandan a harmonización das necesidades da economía e do desenvolvemento con estratexias coherentes de mantemento do patrimonio cultural e natural recorrendo a orientacións e instrumentos axeitados ao patrimonio, tanto a aquel sometido a medidas de protección rigorosas como ao resto dos bens aos que non alcanza esa protección, singularmente considerados ou como elementos das paisaxes culturais. Evitar as actividades e usos prexudiciais para as paisaxes, que están indisolublemente vinculadas ás formas de utilización do territorio, require recorrer a estratexias que definan os usos desexables e os non desexables e que limiten as repercusións negativas. (Blanco-Rotea, Nieto Freire e Sánchez- Carretero, 2021: 49) No ámbito europeo estableceuse na normativa unha concepción integral do patrimonio cultural na que se potencia a relación entre o patrimonio e a súa contorna e na que a protección non se limita ao material dos bens, senón que se estende á conservación integrada, co obxectivo de ponderar as distintas políticas e que estas teñan en conta os aspectos específicos derivados da protección e xestión do patrimonio cultural. Na Recomendación do Comité de Ministros aos Estados membros sobre a estratexia para o patrimonio cultural en Europa no século XXI aténdese especialmente á compoñente do desenvolvemento territorial e económico, que se centra na relación do patrimonio cultural co desenvolvemento territorial, a economía e a gobernanza territorial. Aplicar o principio de conservación integrada e garantir que se teña en conta o patrimonio nas políticas de desenvolvemento, uso do solo, medio ambiente e enerxía, require adoptar políticas e medidas lexislativas que faciliten o enfoque integrado dende e cara ao patrimonio. (Blanco-Rotea, Nieto Freire e Sánchez-Carretero, 2021: 60) Enténdase medio ambiente como «conxunto de compoñentes físicos, químicos, biolóxicos e sociais capaces de causar efectos directos ou indirectos, nun prazo curto ou longo, sobre os seres vivos e as actividades humanas», como o definiu 1 https://consellodacultura.gal/publicacion.php?id=4423. 7 a Conferencia das Nacións Unidas sobre Medio Ambiente (1972); a mesma organización que recoñeceu en 2022 o dereito das persoas a un medio ambiente saudable como un dereito humano. A complexidade do proxecto Gama e dos posibles efectos sobre o medio ambiente, entendido dese xeito, fixo necesario contar para a elaboración deste informe con especialistas dotados de competencia para analizar os distintos aspectos que atinxen á implantación do proxecto —sociais, económicos e da produción industrial, e os seus efectos— e mais atender ás súas sinerxías, polo que o CCG acordou a creación dunha Comisión técnica temporal (CTT) para a elaboración dun informe sobre o proxecto para a implantación dunha industria de fibra téxtil a base de celulosa e as súas infraestruturas asociadas, coa seguinte composición: • Teresa Nieto Freire: coordinadora da CTT e responsable da análise dos efectos sobre o patrimonio cultural e as cuestións sociais • Eduardo Corbelle Rico: coordinador técnico e responsable da análise dos efectos sobre o patrimonio natural e o medio ambiente • Rebeca Blanco-Rotea: paisaxe cultural • María Josefa Fernández Sanjurjo: edafoloxía • Ana Isabel García Arias: economía, socioloxía e política agraria • Horacio García: impacto hidrolóxico • Juan Manuel Lema Rodicio: emisións e contaminación ambiental • Edelmiro López Iglesias: desenvolvemento rural • Xosé Manuel Santos Solla: turismo • Sonia Villapol Salgado: efectos sobre a saúde O corpo do informe intégrano os textos técnico-científicos elaborados polos compoñentes da Comisión, que de maneira xeral asinan individualmente; dous capítulos foron elaborados en parzaría por varios membros, ao consideraren que as materias requirían unha análise integradora. O número final de traballos redactados é de oito, aos que se engade esta «Introdución», unha «Contextualización» do debate técnico e social arredor do proxecto Gama e unha síntese coas «Conclusións» acadadas. Naqueles traballos nos que os autores contaron con colaboradores externos á Comisión, a participación destes está recollida no texto correspondente. 8 Para a elaboración do informe contouse coa documentación do expediente sometida a información pública o 20 de febreiro de 2024 pola Secretaría Xeral de Industria, dispoñible na ligazón (https://economia.xunta.gal/transparencia/infor macion-publica/proxectos-industriais-estratexicos?content=expediente_0005.html), e coa documentación da memoria xustificativa económica presentada pola empresa para solicitar a declaración de proxecto industrial estratéxico (PIE).

O patrimonio arqueolóxico e cultural de Galicia. 2.- A publicación deste informe, coas súas recomendacións e medidas propostas para evitar o dano sobre o patrimonio cultural e natural, para o acceso e maior toma de conciencia da cidadanía galega en relación coa necesidade de protección das fragas e dos xacementos arqueolóxicos de Galicia. Ante estas solicitudes e no contexto de proliferación de plantacións de especies de crecemento rápido que se está a producir en Galicia, mais tamén da demanda social de diferentes colectivos, como as comunidades, o tecido asociativo, as administracións locais e particulares, e de persoas físicas e xurídicas que en gran medida responden á defensa dos valores do territorio, valores estes de tipo social, ambiental e cultural, así como da propia paisaxe, a Comisión Executiva do Consello da Cultura Galega (CCG) acordou en marzo de 2021 a creación dunha Comisión técnica temporal, coordinada por Rebeca Blanco-Rotea e integrada polos seguintes especialistas de diferentes disciplinas: Paula Ballesteros Arias, Eduardo Corbelle Rico, Teresa Nieto Freire (coordinación técnica), Pablo Ramil Rego, Xosé Manuel Santos Solla e Xosé Ignacio Vilaseco Vázquez, á que se encomendou a elaboración dun Informe sobre o impacto dos cultivos forestais con especies de crecemento rápido no patrimonio natural e cultural de Galicia. Os membros e o informe debían atender de forma conxunta as demandas achegadas ao CCG, analizando de forma obxectiva, técnica, plural, rigorosa e construtiva o obxecto destas, a realidade deste tipo de actividade, a afección real ao patrimonio natural e cultural, especialmente ás paisaxes culturais, e facelo de maneira propositiva, é dicir, intentando propor alternativas que melloren a situación do patrimonio en Galicia, especialmente das paisaxes culturais, e minimizando o impacto producido nelas por este tipo de plantacións. Este informe artéllase en varios puntos que analizan a cuestión forestal en Galicia: a conflitividade social arredor das plantacións forestais, a cuestión forestal no contexto das políticas territoriais, os efectos dos cultivos forestais sobre a biodiversidade, o patrimonio cultural do monte, a protección dos bens patrimoniais ante da xestión forestal e o patrimonio como recurso cultural neste contexto, aspectos que aportan unha visión xeral derredor da situación do monte en Galicia e de como lle afectan os cultivos forestais de crecemento rápido. Con todo iso, recóllense unha serie de conclusións que mostran a situación galega, para intentar achegar recomendacións que eviten as afeccións deste tipo de cultivos ao patrimonio cultural e natural na comunidade galega. A elaboración deste informe foi complexa, pois estaba suxeito a unha realidade poliédrica na que se entrecruzan diferentes visións, intereses, necesidades e realidades e foi necesario acadar consensos que tivesen sempre en perspectiva a encomenda do informe e a visión plural e obxectiva dos membros que integraron o equipo de traballo.
