SOIL STABILIZATION BY USING CEMENT

Abstract

Soil stabilization of soil is done by mixing Portland cement with water and compacting the mix to attain a strong material. The material obtained by mixing soil and cement is known as soil-cement. The soil cement becomes a hard and durable structural material as the cement hydrates and develops strength. Cement stabilization is done while the compaction process is continuing. During the compaction process we use some amount of cement. Some void space can be found in soil particle. Cement is just like paw, so cement can fill the void space of soil easily. As a result, void ratio of soil may reduce. After this primary tasks, when we add water in the compaction the cement reacts with water and become hard. So unit weight of soil is also may increased .Soil-cement is sometimes called cement-stabilized base, or cement-treated aggregate base. We used standard proctor test for laboratory experiment, in the laboratory experiment, we added .8%, 10%, 12%, 14%, water in the soil. From the observed data we found that for a certain limit with the of water content the value of dry density in increased, after attaining a peak point the value of dry density in decreased when we increase the amount of moisture content. From the peak value of the graph we determined maximum dry density and optimum moisture content. We continued the same experiment for different percentage of cement mixing with soil. From the experimental value we observed that maximum dry density of the sample in increase with increasing percentage of cement with sample.
