Estudio del comportamiento de un suelo arcilloso estabilizado por dos métodos químicos (cal y cloruro de sodio)

Abstract

The present research aims to know the behavior of a clay soil stabilized with Lime and Sodium Chloride with percentages of 2.5% - 7.5% and 12.5%. The soil sample was extracted from a test pit at 1 m depth in the city of Puyo, and used the entire volume of the calicata to perform the laboratory tests with altered and unchanged samples. For the analysis of the properties of the soil under normal conditions the tests were carried out: Cone and sand of Ottawa, Moisture content and Unconfined Compression. In order to analyze the properties of the natural soil and stabilized soil, the following tests will be performed: Specific Gravity, Actual Density of Stabilizing Agents, Atterberg Limits, Resistance to Simple Compression (qúlt and qadm), Modified Próctor method D and capacity of support of the graund (CBR). Sodium Chloride was used granular salt which was pulverized for a better reaction with the clay particles. In the Simple Compression Resistance test, blocks were perform and tested at 7, 14 and 21 days. With the right tests, it was compared the behavior of the soil under normal conditions with the soils stabilized with Lime and Sodium Chloride and determined its optimal percentage with each stabilizer.
