Engineering properties of Self-cured Geopolymer concrete binded with supplementary cementitious materials

Abstract

The majority of recent research has been on creating substitutes for traditional portland cement concrete, which uses an excessive amount of natural resources and pollutes the environment with carbon emissions. In this sense, Geopolymer concrete is a unique substance that might lessen the negative effects of conventional portland cement production. The features of fly ash-based Geopolymer concrete that was heated to a high temperature have been the subject of several earlier research, although heat curing is another energy-intensive method. In order to provide a thorough understanding of self-cured Geopolymer concrete confined with industrial by-products such as fly ash and ground granulated blast furnace slag, this study focuses on the engineering properties compressive strength, split tensile strength, modulus of rupture, density, and ultrasonic pulse velocity, as well as the analysis of test results. The laboratory results on various Geopolymer concrete mix designs compared to portland cement concrete demonstrated that Geopolymer concrete has produced results that are superior to those of conventional concrete. The results of the destructive test were compared to the results of the non-destructive test, which exhibit excellent correlation, and an R2 coefficient value of 0.9801 was obtained.
