The results show that. The added rice husk ash and firing temperature of 900 0C showed the best properties for density, porosity, water absorption, conductor electricity and pH, equal to 1.28 g/cm3 21.10%, 35.60%, 0.14 dS/m and 6.97, respectively. The added bagasse ash and firing temperature of 900 0C showed the best properties for density, porosity, water absorption, conductor electricity and pH, equal to 1.61 g/cm3 34.70 %, 25.30%, 0.13 dS/m and 7.50 respectively.
