Effect of cement and corn cob ash on UCS and direct shear test of clayey soil

Author(s): Gurjap Singh Somal, Gurdeepak Singh, BS Walia
Abstract: Soil present in nature may have no. of strength deficiencies. Thus needs to be stabilized and its properties needs to be modified in appropriate way to gain high strength characteristics. Large scale agricultural commodities producing nations are facing problems due to agricultural wastage produced like rice husk, corn cob etc. As corn cobs does not decompose easily results in causing numerous problems to surroundings as well as environment. Corn cob ash produced by burning corn cobs. Corn cob ash rich source of silica and thus having large tendency to behave like pozzolana make it suitable for using as cementious material. Objective and motive of study investigation is to investigate Soil: Cement: Corn Cob Ash mixture strength improvement by seeing its strength through UCS, DIRECT SHEAR TEST of stabilized soils. Corn cob ash added in varying amount alongside optimized cement value. For optimum mixture cement 2% and corn cob ash 6% compressive strength enlarged by 310% and 402% equated to virgin soil strength for 7 and 14 days curing spell respectively. Shear strength for optimum mixture increased by 64% equated to virgin soil strength for 14 days curing spell. Consequently Strength parameters were found showing a sufficient improvement in strength features of soil.
