Does Geopolymer Concrete have the Scope of Effective Utilization in Rigid Pavements? - A Definite Review

Abstract

Rigid pavement construction primarily resorts to the utilization of concrete incorporating cement as the integral material. The carbon footprint associated with cement production engendered the conception of modern binders in the construction industry. Furthermore, the substantial amount of waste generation in conjunction with the rapid depletion of natural resources conceived its effective utilization in the pavement sector. Geopolymer concrete (GPC) is the modern binder whose scope in rigid pavement construction is being studied extensively considering its sustainability and performance. Although research portrays comprehensive study on various wastes as the aluminosilicate source for synthesizing geopolymers, yet its application in rigid pavements is rather a newer approach as compared to structural members especially in the Pavement Quality Concrete (PQC) layer. This review presents a precise scenario of GPC utilization in pavements and is definite and specific in terms of its representation. The idea of this article is to introduce the readers to an alternative binder that is relatively contemporary and effective when used in rigid pavement construction.
