This study was conducted to evaluate the effect of pumice on some physical and mechanical properties of clay bricks fired under varying firing temperatures. Brick samples comprising varying amounts of pumice were prepared, mixing the clay material pumice in gradually increasing ratios. Increasing rate of pumice gradually decreased bending strength, compressing strength, density, firing shrinkage and heat conductivity; and gradually increased the water adsorption of the brick produces under reach of 800, 900 and 1000°C. It was concluded that pumice can be safely used to improve mechanical and physical properties of the final material, provided that the ration of pumice to clay should not be exceed unity.
