Dosagem de misturas de solo-cimento-cinza de casca de arroz através de ensaios destrutivos e não destrutivos.

Abstract

The environmental concem related to the indiscriminate extraction ofBrazilian natural resources and the ceaseless agricultural and industrial waste generation became a serious problem demanding for a quick solution. So this work was done in order to minimize the environment degradation by accomplishing dosage study of mixtures made of soil-cement- rice husk ash through destructive and non-destructive methods. For this purpose, the different mixtures of soil-cement-rice husk ash were tested for compaction and the specimens molded at the optimum moisture content. Afterwards they -were submitted to compression tests at 7 days old and to ultrasonic pulse velocity tests.The obtained results showed that the sandy soil partially substituted by 2,5%; 5%; 7,5% and 10% of ash and stabilized with 7%, 10% and 13% of cement pointed out its promising use as an altemative material for use in both rural and urban constructions.
