REPLACEMENT OF SAND WITH FLY ASH

2020-4-4  During the last few years, cement companies have started using fly ash in manufacturing cement, known as ‘Portland Pozzolana Cement’, however in Indian scenario the overall percentage utilization remains very low and most of the fly ash is dumped at landfills. Fly ash is generally used as replacement of cement, as an admixture in concrete and in manufacturing of cement. Concrete containing fly ash as partial replacement of cement poses problems of delayed early strength development. All the previous studies have reported effect of sand replacement by fly ash on concrete and mortar with Ordinary Portland Cement. As Government of India is encouraging the use of Portland Pozzolana Cement, PPC is used in the present study. Concrete containing fly ash as partial replacement of fine aggregate will have no delayed early strength development, but rather will enhance its strength on long-term basis. Also fine aggregate occupies about 25% to 40% of total volume of concrete, and hence provides great opportunity to utilize the waste materials, like fly ash for replacement in big volumes. The need of fly ash utilization arises out of the fact that good quality natural river sand
