Abstract

This paper is a part of experimental research to access the strength and durability performance of fly ash based geopolymer concrete with fine aggregate substituted with M-Sand. Geopolymer concrete is an ecofriendly concrete which has a weaker carbon footprint than that of traditional concrete. In this experimental study, fly ash has been substituted for cement; manufactured sand has been replaced for natural river sand. Fly ash has been used in geopolymer concrete and cured under multiple curing procedures. It was noted that use of geopolymer concrete not only overcomes its greenhouse footprint but, also enhances its strength and resistivity to adverse acids. The scope of this research work was limited to analysing several strength parameters such as compressive strength, split tensile strength and flexural strength along with the durability parameters like acid resistance, sulphate and chloride attack, carbonation effect, water absorption analysis and rapid chloride permeability tests.
