EXPERIMENTAL INVESTIGATION ON BEHAVIOUR OF FLYASH BASED CONCRETE BY REPLACING SAND WITH M-SAND AND CEMENT WITH FLY ASH

Abstract

As we know that round the world wide every developing country along with our country the global consumption of manufactured sand as an alternative for natural sand is used extensively because of high demand and scarcity of natural sand. In this regard to understand the behavior of concrete specimens with M-sand and fly ash is studied experimentally. The use of M-sand the density will be more which ultimately results in increase of Strength. The use of fly ash in concrete is desirable because of benefits such as increased workability, reduction in cement consumption and decreased permeability. The use of fly ash leads to reduction in early strength of concrete but there is increase in long term strength. This experiment investigates the strength of concrete in 7days, 28days and 56days curing period containing 0%,20%,40% & 60% of fine aggregate (Sand) replacing with M-sand and 0%,20%,40% &
60% of cementitious materials by fly ash along with Super plasticizer Hyper Fluid plus 3 Admixture is used for the grade M-45 (PSC). The concurrent use of these materials will lead to environmental and economical benefit.
