Propriedades físico-mecânicas de tijolos de solo-cimento com incorporação de resíduos vegetais.

Abstract

The aim of this research was to study the effect of the vegetable wastes addition under the physical and mechanical properties of soil-cement bricks. It was used two types of wastes (rice husk and Brachiaria brizantha one).The cement Portland content used on the soil stabilization was 10%. The vegetable wastes contents were 0%, 10%, 20%, 30% and 40% added in substitution to the cement. The bricks were submitted to the compression tests and to the water absorption test. The best results, in terms of compression strength and water absorption capacity were reached by the 10% addition of vegetable wastes in substitution to the cement. The results suggest the promising use of these wastes, at the 10% content, without the compromising of the mechanical properties related to the resistance and to the durability of soil-cement bricks.
