Solos lateríticos estabilizados com cimento através da metodologia da ABCP.

Abstract

This paper aims at studying the Resistance to Simple Compression, Durability and California Bearing Ratio using laboratory tests of tropical red soils, stabilized with several contents of pozzuolanic Portland cement. Characterization tests were carried out in the identification of soils. Compaction tests, dosed in cement contents varying from 0% to 9% in Optimum Moisture Content and 2% near optimum, were submitted to a cure period during 7 days. Subsenquently, the Resistance to Simple Compression and Durability were measured. For measuring the California Bearing Ratio the cement contents varied from O to 5% in the same anterior moisture conditions. mong the results we can observe that the tests of Resistance to Simple Compression indicated cement contents 5% for Canguaretama soil and 9% for the Mipibu and Pipa soils to obtain the minimum resistance as specified by ABCP. However, cement contents from 3 to 5% were shown to be sufficient to stabilize soils using the Durability tests by weting and drying. Therefore, we can conclude that the durability test seems to be more adequate to determine the cement content of tropical red soils. The results make us believe that there is an interdependence between the Resistance to Simple Compression and the California Bearing Ratio.
