Hurdles with self–cured Geopolymer Composites in Indian scenario

Abstract

Ordinary Portland cement (OPC) production is boosting global warming very speedily. Therefore, geopolymer concrete is receiving huge attention as an alternative to traditional concrete because it develops without the use of OPC. Majority of the previous publications suggest that high-temperature curing required to gain higher mechanical strength and better durability properties, which is not feasible for cast-in-situ work. This obstacle has been overcome by adding calcium oxide and reducing silicon dioxide in the geopolymer. In addition, geopolymers also confront many other problems such as cost of construction, efflorescence and utilization of harmful chemical etc. that can’t be easily overcome. This literature makes an effort to identify some hurdles with the geopolymer composite in the Indian scenario. It concludes geopolymer composites will take some more time to completely replace conventional composites and requires some more improvement.
