Durability Studies on the Hybrid Fiber reinforced Geopolymer concrete made of M-sand under ambient curing

Abstract

Abstract In the recent decade, there have been a lot of significant developments made in the area of Geopolymer concrete. Geopolymer concrete has been proved for its remarkable durability properties but when alterations are done to the conventional geopolymer concrete through the incorporation of fibers, the durability of the fiber reinforced concrete is uncertain. In this analysis, high elasticity modulus and low elasticity modulus fibers were inserted into geopolymer concrete made of M-sand. As ambient curing is favored in this study, geopolymer concrete is GGBS dependent. As an alkali solution, a mixture of sodium hydroxide solution and sodium silicate solution is used. Durability properties such as water absorption, sorptivity, rapid chloride penetration test, resistance to HCL attack, resistance to H2SO4attack, resistance to sulphate and marine attack are determined in this study. Significant observance has been made with respect to different proportions of glass fiber and polypropylene fiber. Glass fibers yielded fairer results compared to the polypropylene fibers. This study reviews the scope of the use of hybrid fibers made of M-sand in Geopolymer concrete.
