Experimental Investigation of Geopolymer Concrete Using Fly Ash and GGBS

Abstract

This experimental study was undertaken to study the strength characteristics of Geo-polymer concrete. This experiment involves study to reduce the greenhouse gas emissions by implementing use of alternative material to cement. Five to eight percent of the world's man- made greenhouse gas emissions is from the cement industry itself. It is an established fact that the greenhouse gas emissions are reduced by 80% in Geo-polymer concrete compared to conventional Portland cement manufacturing, as it does not involve carbonate burns etc. Thus Geo-polymer based Concrete is highly environment friendly and the same time it can be made a high-performance concrete. In the present study, 100% replacement of conventional ordinary Portland cement is made by using ASTM class F fly ash, Ground granulated blast furnace slag and catalytic liquids (or AAS) to prepare Geo-polymer concrete mixes. In our present study we evaluated strength characteristics of Geo polymer concrete by varying the molar concentration (6M, 8M, and 10M) and varying percentage of binding material. The work has been done to structural specimen like cylinders and cubes and evaluated compressive, split tensile strength for different binding material proportions and solution concentration.
