Study on Characteristics of Geopolymer Concrete with E-Waste

Abstract

The usage of industrial by-products in construction industry can be reduced the pollution effects on environment. Geopolymer concrete is a concrete in which Portland cement is fully replaced by fly ash and GGBS (Ground granulated blast furnace slag). The present study covers the use of E-Waste as partial replacement of fine aggregate in Geopolymer concrete. Sand is replaced with E-Waste at 10, 20 and 30 percentage.Alkaline liquids used in this study are the solutions of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). Molarity of sodium hydroxide (12M) is considered. Fly ash and GGBS were used in the combination of 90 and 10 percent respectively. This study conducted to know the compressive and tensile strengths of Geopolymer concrete with E-waste and to compare the same with Geopolymer concrete. It has been revealed that 20 percentage replacement with E-Waste attained higher strength than the normal Geopolymer concrete of M40 grade.
