EXPERIMENTAL STUDY OF HIGH VOLUME FLY ASH IN CONCRETE

Concrete is the primary requirement for construction of any structure and hence is listed as the world's second most used material.Cement is the only binding material in the conventional concrete whose production causes emission of large amount of greenhouse gases like CO 2 which leads to Global Warming.Hence, in order to overcome these problem, cement can be partially replaced by the by-product of power plant's fly ash which also has binding property like cement its production is more economical, sustainable and eco-friendly.There are number of advantages of using fly ash in concrete to increase strength parameters in structures.The chief goal of the present investigation is to study mechanical behaviour of the HVFAC.In this study, the behaviour are studied with various partial replacements of cements like 30%, 40%, 50%, 60%.In contrast to conventional concrete, 50% replacement showed overall equal strength in 28 days.The results are taken for 7 and 28 days.
