Resumo
The aim of this research was to evaluate the effect of rice
and Brachiaria brizantha husks on physical and mechanical
properties of soil-cement mixtures and, consequently, to analyse
their technical feasibility to manufacture alternative building
materials for agricultural purposes. Husks were ground, sieved,
and treated in lime solution and soil submitted to characterisation
tests according to Brazilian standards. The plant residues were
added in substitution to the cement. The cement content and
residues ranged from 100% of cement and 0% of waste, to 60%
of cement and 40% of waste. Following, cylindrical specimens
were molded and submitted to compression test at 7, 28, and 56
days, and water absorption test seven days from molding. The
results showed that the mixtures obtained from the partial
substitution of cement by 10% waste are technically feasible as
raw materials for constructive elements manufacturing without
structural function, such as bricks and blocks, for agricultural
buildings.
