Abstract

Abstract

The increased production of Portland cement causes great concern to environment because of its high carbon foot print. Geopolymer concrete is a new invention in the world of concrete in which cement is totally replaced by industrial waste and byproducts like fly ash. Geopolymer concrete is environment-friendly material for construction because of its reduced carbon foot print and also it is found to be durable. In this study, strength and durability characteristics of geopolymer concrete are studied with partial replacement of waste steel slag obtained from steel plants. Steel slag is impregnated in varying percentages of 5–15% instead of fine aggregate in geopolymer concrete prepared with sodium silicate and sodium hydroxide used in a ratio of 1.8:2.5, and various properties obtained were analyzed.

 

Keywords: Geopolymer, fly ash, steel slag, fine aggregate
