MoreTo overcome from this crisis, partial replacement of cement with fly ash and fine aggregate with Thermocol can be an economic alternative. This project focuses on investigating the characteristics of M25 grade of concrete with cement partially replace with fly ash 35%, 40% and fine aggregate replace with thermocol 0.2%,0.3% respectively.
MoreThe fly ash generation in India through thermal power plants in 2014-15 was about 185 million tons and utilization was 55.69% [5, 6]. Research has been carried out for the use of waste material like bottom ash, construction and demolition waste, copper slag, iron and steel slag as a fine aggregate [7, 8, 9, 10].
