Abstract: This work presents the comparative study of pure clay with that blended with rice husk in Enugu State, Nigeria. This research was carried out to investigate its physical properties, such as; modulus of plasticity, porosity, bulk density, water absorption, making moisture, modulus of rupture, shrinkage and apparent density. In order to ascertain the influence of rice husk on these properties of the clay in the area in question. The results obtained revealed that the blended clay with rice husk and pure clay were fired at furnace to the turn of 900°C, 1000°C, 1100°C and 1200°C respectively. They were then tested for apparent density, porosity, and modulus of rupture and water absorption capacity. The results obtained showed that the maximum service temperature of the blends was presented to be the best under a given temperature. There was also observed decrease in the bulk density, shrinkage with an increase in the plasticity.
