Partial replacement of fine aggregate with Copper slag and marble dust powder in geo-polymer concrete: A review

Abstract

-As of late the ascent of substantial creation costs has consistently been a worry of substantial makers and customers. Using current waste to override concrete and some poIn ongoing years the ascent of substantial creation costs has consistently been a worry of substantial makers and buyers. Using present day waste to override concrete and some bit of all out can diminish its cost and environmental dirt of all out can decrease its cost and natural tainting. The mark to the purpose of this paper to audit the shot at powder made from marble dust close by the copper slag as an in part substitution to fine aggregate all out in geo-polymer concrete. Marble dust powder was used in mix in comprise copper slag as in part substitution to fine aggregate in level of 10%, 20%, 30%, 40% and 50%. The strength of geo-polymer concrete was tested after 7 & 28 days. Result shows that compressive strength is increased after the replacement of 60% of copper slag and marble dust powder to fine aggregate and also flexural strength and split tensile strength increases strength upto 60% and 80% after replacement. These discoveries of the examination express that powdered marble dust will be utilized as the conceivable substitution material to fine aggregate to give maximum strength copper slag geo-polymer concrete.
