Abstract
The main objective of this paper is to provide an alternative to conventional cement and lime for production of fly ash brick. Two widely used fly ash bricks (fly ash cement brick and fly ash lime brick) were selected for this experimental study. However, the brick specimen of size 230x 110x 90mm was cast for diff mix proportions of raw material for testing. The experimental study was performed in two stages. In first stage, cement partially replace by granite powder in fly ash cement brick. And in second stage, lime partially replace by granite powder in fly ash lime brick. In both stages, replacement of cement and lime by granite powder in range of 0 to 15 % with interval of 5% was done. The compressive strength of fly ash bricks at the age of 7, 14 and 21 days was obtained at room temperature. On studying results, it was found that the maximum compressive strength is obtained at 10% replacement of granite powder in both type of fly ash brick and highest compressive strength was found in fly ash cement brick with 10% replacement of granite powder from overall tested brick. It was concluded that a sustainable fly ash brick can be produced by replacing 10% granite powder, after increasing percentage of granite waste more than 10% strength was decreases in both fly ash brick.
