An Experimental Study on Mechanical Properties of Concrete by Partial Replacement of Cement with Rice Husk Ash and Silica Fume

In this experiment cement was exchanged with varying amounts of rice husk ash and silica powder sf such as 10%,15% and 20% to examine the features of the resulting concrete according to research M30 grade demonstrates great compressive and split tensile strength and performs best in 15% transfer the effects of substituting 15% of cement with RHA and SF on the overall properties of concrete are demonstrated in detail which contributes to a better understanding and development of building practices.
