Aproveitamento do bagaço de cana-de-açúcar visando sua utilização para fins de obtenção de compósitos de biomassa vegetal-cimento.

Abstract

This work synthesizes some results about the use of sugar cane bagasse as a component to alternative material. It can result in a good building material, provided that problems of chemical incompatibility of fiber and cement are solved. The sugar cane bagasse fibers were selected, after hot water washing-up, and then submitted to a “mineralization” treatment with inorganic salts (5% sodium silicate and 30% aluminum sulphate). The main objective was to evaluate treatments efficiency by means of both water absoption and compressive resistance tests, the specimens moulded in the proportion of 1:2:0.20:0.78 (cement:sand:fiber:water).
