Data for the Effect of different supplementary cementitious materials on compressive strength of concrete

In this rapid urbanization age, cement concrete is one of the most popular and demanding building material. Concrete contains about 12-15 % cement as one of the components. Globally, the annual cement production causes about 7% carbon dioxide contribution in world wise. CO2 emission. which makes the concrete production industry as a source of global warming. The objective of this study is to find out a way of mitigation of environmental hazards generated due to its production. Supplementary cementitious materials (SCMs) are those materials which are generated from different industries like fly ash (FA), rice husk ash (RHA), silica fume(SF) and ground granulated blast furnace slag (GGBFS), etc. These materials have the virtue of improving strength of concrete in higher age if used as a replacement of cement in concrete. During experimental investigation, total sixty-six cubes of size 15cmx15cmx15cm were prepared to determine the strength of cubes for different curing time of 14, 28 and 56 days. Ash Fly and RHA separately used for partial cement replacement with the proportions of 15%, 20%, 25%, 30% and also SF with 10%, 15%, 20% then, 14 days and 28 days and 56 days’ compressive strengths were calculated by compressive testing machine.
