Abstract: Due to pozzolanic reactivity, Rice Husk Ash is used as a supplementary cementing material in concrete. It has economical and technical advantages to be used in concrete. I am going to partially replace cement by the use of RHA by 5 %, 10 % & 15 % & 20 % by weight of cement in four different experiment to find out the maximum strength and compare it with the strength of normal concrete by using the grade of M30 at the days of 7days, 14days & 28 days. This research therefore is an investigation of the performance of the concrete made of partially replacing OPC with RHA on the structural integrity and properties of RHA concrete.
