Abstract: The utilization of substitutes aggregats like silica sand is a characteristic advance in solving some common aggregate. The examination on substitute material for concret making began before 50 years. concret produced using silica sand as partial additional of River sand will be studies for workability, compressive strength, Flexural strength and split strength, and modulus of elasticity. I will used of silica sand as partial additional of River sand by various rate for making concert of grade M-40. The rate of additional substitution will be 0%, 25%, 50% and 75% with common River sand. For making concrete OPC-53 grade cement is utilized. cube shapes, cylinder and beams will cast and testing compressive strength, Split strength, and flexural strength just as for durability properties. Ideal additional of silica sand can be utilized in structural concerts. GGBS is a Ground Granulate Blast Furnace slag, which is in powdered forms, In concert, it help to decrease the damage caused by an alkali silica chemical attack and also gives higher attrition to chloride. Therefore 35% of GGBS is replacement to cements.
Keywords: Silica Sand and GGBS.
