An Investigation on Mechanical and Durable Properties of Eggshell Based Geopolymer Concrete using Flyash and GGBS

Abstract

This research work represents an investigation of the mechanical, durable properties and microstructure of geopolymer concrete mixed using Eggshell powder, class F fly ash (FA) and Ground granulated blast-furnace slag (GGBS). An optimal combination of FA, GGBS and Eggshell powder was determined using the compressive strength tests of geopolymer pastes and to find the durable properties like acid attack test and sorptivity test were conducted with various different replacements of FA with GGBS and Eggshell powder. The test results are to be taken on the mix proportions of geopolymer concrete various mix to be taken at 28,56, and 90 days respectively. This paper aims to examine the effects of chemical changes of reaction generating liquid on the strength and durable properties done to analyse the microstructure of the mortar through SEM, XRD, FT-IR and porosity assessments. The porosity analysis enabled us to indirectly verify the remarkable mechanical performance obtained by the activation of polymerization according to the chemical components of the Reaction Generating Liquid.
