Contrastive Analysis on Mechanical Properties of M Sand and River Sand Cement Mortar Bricks With Partial Restoration of Rice Husk Ash

Abstract

Normally Rice Husk Ash (RHA) is treated as agricultural waste that do not afford any human feed products across the globe, these kind of agricultural waste can be converted into a convenient product and also M sand is used as a substitute for the river sand, the proportions of river sand from 100%, 75%, 50%, 25%, 0% were restored by M sand, along with that rice husk ash in various proportions from 0%, 5%, 10%, 15%, 20%, 25%, 30% to determine the optimum percentage of rice husk ash without affecting strength properties of bricks. The optimum restoration of 35% of RHA delivered the average compressive strength of 5.34 MPa which is higher than that of common buildingbricks.
