Resumo: The aim of the present work was to analyze and compare the potential of the use of rice husk ash (CCA) and rice husk silica (SCA) in separate mixtures, as a partial replacement material for the cement and also the reduction of the same in different traces of concrete. In order to do so, a reference trait was produced, and from this the substitutions and partial reductions of cement were carried out at different levels. The analyzes allowed to identify which of the two pozzolans studied presented the best performance regarding the axial compressive strength, water absorption, voids index, specific mass and concrete abatement. The study showed that the higher the cement substitution rate for some of the pozzolans, the greater the consistency acquired by the concrete, losing its fluidity. The mixtures presented little difference between them in the voids index, specific mass and water absorption. The mixture that achieved the highest axial compressive strength was S2 (10% SCA), at 91 days of age, with 25.23% more resistance than the reference concrete. However, the S6 blend (10% SCA + 10% reduction) was most successfully replaced and reduced the amount of cement thus practically maintaining the same characteristics as the reference.

Para ello se elaboró ​​una mezcla de referencia, y con base en ella se realizaron sustituciones y reducciones parciales de cemento en diferentes niveles. Los análisis permitieron identificar cuál de las dos puzolanas estudiadas presentó el mejor desempeño en términos de resistencia a la compresión axial, absorción de agua, índice de huecos, masa específica y asentamiento del concreto. El estudio demostró que cuanto mayor es la tasa de sustitución del cemento por una de las puzolanas, mayor es la consistencia que adquiere el hormigón, perdiendo su fluidez. Las mezclas mostraron poca diferencia entre ellas en términos de contenido de huecos, masa específica y absorción de agua. La mezcla que logró mayor resistencia a la compresión axial fue la S2 (10% SCA), a los 91 días de edad, con un 25,23% más de resistencia que el concreto de referencia, considerándose la mezcla de mejor desempeño.O  trabalho buscou analisar e comparar o potencial do uso da cinza de casca de arroz (CCA) e da sílica de casca de arroz (SCA) em misturas separadas, como material de substituição parcial do cimento e também a redução do mesmo em diferentes traços de concreto. Produziu-se um traço referência, e a partir dele realizaram-se as substituições e reduções parciais de cimento em diferentes teores. As análises permitiram identificar qual das duas pozolanas estudadas apresentou o melhor desempenho. O estudo mostrou que quanto maior for o índice de substituição de cimento por alguma das pozolanas maior será a consistência adquirida pelo concreto, perdendo a fluidez. As misturas apresentaram-se com pouca diferença entre si quanto ao índice de vazios, massa especifica e absorção de água.  O estudo mostra que os traços com SCA tiveram resultados superiores aos traços com CCA, também, que é viável a substituição parcial do cimento por qualquer um dos dois tipos de pozolanas estudadas, aumentando a resistência a compressão axial do concreto, conseguindo benefícios técnicos e economia financeira, uma vez que diminui o consumo de cimento e consegue-se dar um fim adequado a esses resíduos.UFSC - Federal University of Santa Catarina2024-02-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/622610.29183/2447-3073.MIX2024.v10.n1.17-28Mix Sustentável; Vol. 10 No. 1 (2024): Mix Sustentável (edição regular); 17-28MIX Sustentável; v. 10 n. 1 (2024): Mix Sustentável (edição regular); 17-282447-30732447-0899reponame:Mix Sustentável (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://ojs.sites.ufsc.br/index.php/mixsustentavel/article/view/6226/6049InternacionalInternacionalInternacionalCopyright (c) 2023 Cristiane Carine dos Santoshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessdos Santos, Cristiane CarineFischer Martins, Paulo Vinicius2024-05-06T00:41:45Zoai:ojs.sites.ufsc.br:article/6226Revistahttp://mixsustentavel.paginas.ufsc.br/apresentacao-2/PUBhttp://ojs.sites.ufsc.br/index.php/mixsustentavel/oailisiane.librelotto@ufsc.br||mixsustentavel@gmail.com2447-30732447-0899opendoar:2024-05-06T00:41:45Mix Sustentável (Online) - Universidade Federal de Santa Catarina (UFSC)false
