Effect of Lime and Cement on Unconfined Compressive and Shear Strength of Soil in Baleli and its Vicinity

Abstract

This study was carried out with an intention to observe any sign of improvement of clayey silty soil due to addition of lime and cement. This paper focuses on the primary research of using blends of lime and cement on the soil of Baleli and its vicinity region to evaluate the features of cement and lime at the shear strength of unsaturated soil through carrying out direct shear and unconfined compression tests on soil samples. Soil admixed along with natural or artificial admixtures is one of the techniques to improve its physical characteristics, consequently we need to alter some features of soil that could make it expedient to calculate the bearing ability of the soil and even stabilize the weight bearing potential. The values obtained here are in comparison with unblended soil samples, at 5% admixed soil with cement and lime showed maximum angle of friction and moderate cohesion but shear strength 30.32 psi achieved at this percentage of lime and cement was greater than other percentages. The unconfined strength of this blended soil presented a compression of 86.32 N/mm2 at 0.0503 mm/mm percent strain which is lower than maximum percentages of lime and cement and conclusions are drawn toward the usability of lime and cement as a value effective approach. Soil sample admixed with 7% lime and cement presented less cohesion than those blended with 3% and 5% lime and cement but greater shear strength as compared to all of the samples including simple soil. The unconfined strength of this blended soil presented a compression of 115.32 N/mm2 at 0.0755 mm/mm percent strain which is lower than maximum percentages of lime and cement. As a significance, its miles better to combine distinctive types of soils collectively to improve the soil vitality back ground.
