Abstract

This article presents a review report on the utilization of Geopolymer concrete (GPC) for pavement applications. GPC is a substitute construction material to OPC concrete and is produced by using industrial waste exhausts. The GPC technology has gained its interest of researchers from the last few decades. In the recent times, it has became an alternative material to OPC, due to its renewed interest that is relating to the  green house gases(GHG’s) emissions into the environment by the production of OPC. It is predicted that over 7% of GHG’s are emitted into the atmosphere during the production of OPC and the GPC material has the potential to reduce this amount up to 90%. Further, it is claimed that, this aspect will have an extensive capabilities in the reduction of national interests in GHG emissions of majority of countries all around the world. This review report crucially examines and evaluates the existing research relating to these claims and pivots on the promising utilization of GPC for pavement applications. In addition to the aspect of eco-friendly nature, the existing research recommends that GPC has the capability to deliver superior mechanical strength characteristics like immediate strength development and durable to chemical attacks etc., than OPC. The present study considers and evaluates the utilization of GPC with different grades, materials used for preparing GPC, their strength properties and their sustainability in pavement applications.
