Avaliação da qualidade de tijolos de solo-cimento incorporados com resíduos vegetais pela combinação de testes destrutivos e não-destrutivos.

Abstract

The aim of this research was to study the combination both non-destructive and destructive methods associated to the statistical analysis in order to evaluated the quality of manufactured bricks of soil-cement-vegetable-wastes. It was used Portland cement and it was used husk rice and Braquiaria brizantha one as wastes. The vegetable wastes contents (0%, 10%, 20%, 30% and 40%) were used in substitution to the 10% cement content. The bricks were submitted to the tests in the periods of 7, 28, 56 and 91 days after the moulding. Their mechanical characteristics were evaluated through both non-destructive and destructive methods. Those two methods were associated in order to describe precisely a quantitative parameter so called the “anisotropical resistance”. The results showed that such parameter could be used as a good index for bricks technical quality evaluation. The addition that promoted better technical quality to the bricks was the 10% waste content.
