Avaliação Mecânica de Placas Cimentícias com Substituição do Cimento por Cinza do Caroço de Açaí

Abstract

The general objective of this work is the mechanical evaluation of cement slabs with a view to replacing percentages of the cement with açaí seed ash (ASA). As environmental problems are a reality in today's society, which is a large consumer of natural resources and a generator of waste, açaí seeds, widely found in the Northern region of Brazil and which do not have adequate disposal, in addition to being a material that is difficult to decompose due to their high lignin content (Teixeira et.al 2006), they become an option when thinking about the association between environmental preservation, civil construction and innovation, thus enabling their reuse as an input. The development of the research took place considering the replacement of 5% of the cement with açaí seed ash. Three (3) reference pieces and 3 pieces were molded by replacing the cement with the residue. Compressive strength and flexural modulus were measured. When analyzing the flexural modulus of the parts, it was observed that the parts with the addition of ASA supported 13.5% more than the reference parts.
