Development of High Compressive Strength Fire Brick

Abstract:

This research into the development of high compressive strength brick reports the experiment of the high compressive strength brick made out of alumina and rice husk ash with the following ratios: 40:60, 50:40, 60:40, 70:30 and 80:20, with 10% or 15% of sodium silicate according to weight. The burning temperature was set at 1,000 °C and 1,200 °C. It was found that in term of density, the brick with the ratio of 80:20 with 15% of sodium silicate yielded the highest density with 3.3 g/ cm³. As for the compressive strength, the brick with the ratio of 80:20 with 10% of sodium silicate burned at 1,200 °C yielded the compressive strength of 528 kg/cm². The brick with the ratio of 80:20 with 10% of sodium silicate had the lowest absorption of 15.68%. As for the shrinkage, the brick with the ratio of 40:60 with 10% of sodium silicate had the highest shrinkage of 1.98%.
