Abstract:Reports research on the beneficial utilization of waste husk from rice production. The husk was burned in the furnace at two different temperatures, 400 and 500 C for « hr, and it was observed that all the silica obtained was amorphous at both burning temperatures. The mortars were prepared by substituting cement with husk at 10, 20, and 30 percent by weight. The ratio of (water + superplasticizer)/(cement + ash) was kept constant at 0.57 for all batches. The mortars were stored in sodium sulfate solution until the testing date after the initial 28 days normal curing in water. Compressive and flexural strength tests were carried out on the mortar specimens at 4, 8, and 12 week periods of storing in solution. It was observed that durability and strength of mortars were increased by using rice husk ash.
