Abstract – The increase in emission of carbon dioxide is a matter of concern over decades. The toxic coal waste product like fly ash is being utilized as a binder material in construction industry. The idea of high volume fly ash concrete is used in the research area lately as it is having an immense effect on environment. It is used as a partial replacement of cement whose production leads to huge emission of carbon dioxide. The present work focuses on the strength of high volume fly ash concrete with ages. The compressive strength of different proportions of HVFA concrete at 7, 28 and 56 days and tensile strength for 56 days are analyzed. This also stresses on the weight reduction in each mix in comparison with ordinary concrete. The percentage replacement of cement by fly ash is 40%, 50% and 60%. The effect of high amount of superplastisizer and reduced amount of water in this concrete is studied.
