The study was conducted to determine the potential of rice hull ash as admixture to clay soil to produce brick tiles. Experimental method of research employing a completely randomized design with three (3) treatments and three (3) replications was utilized. Different proportions of rice hull ash materials added in three (3) kilograms of URS Tanay clay soil were considered to determine the weight, size reduction, water absorption capacity, porosity and compressive strength of brick tiles and find its effectiveness. The water absorption capacity of brick tiles is higher at reduce amount of rice hull ask. The porosity and compressive strength of the bricks are not affected by the amount of rice hull ash used as admixture. The quality of brick tiles in terms of texture proved that all treatment were the same mean. The texture of brick tiles was not affected by the proportion of rice hull ash material in three (3) kilogram of clay soil.
