| Summary: | The behavior of sand was found to be governed by its chemical properties rather than its physical properties. Hence, it is important to determine the geochemistry properties of sand besides its physical properties. The thermal applied on the bentonite and kaolin is one of the important external elements for changing soil mechanical characteristics based on mineralogy and stress-strain relationship. It is for considering of mineralogy and mechanical properties of bentonite and kaolin to development a better construction material. To evaluation of bentonite clay and kaolin behavior when subjected to the thermal, several laboratory tests have been conducted to analysis of bentonite characteristics. This project aimed on determining the strength of sand, mixed with 0.25%, 0.5%, 1% and 2 % of bentonite and kaolin with and without thermal added the bentonite and Kaolin for 300'C for one hour. Bentonite and kaolin, in powdered forms, was mix with sand and compacted at optimum moisture content. The strength of the compacted samples was determined from direct shear test. It was observed that the material of bentonite and kaolin increased the cohesion of sand. The result shows that 1% bentonite 300'C gives higher shear strength of sand. This shows that the bentonite can be used to increase the strength soil than kaolin. This due to the fine nature of the materials that could fill the voids in the mixture but also contribute to decrease in friction angles. |
