Use of fly ash as partial replacement of sand in concrete
To overcome from this crisis, partial replacement of sand with fly ash can be an economic alternative. Design mix of M20 grade concrete with replacement of 20%, 40% and 60% of fly ash have been considered for laboratory test i.e. slump test and compressive strength. As per M20 Mix Design in this project we
