Reduction of Setting time of GGBS based Geo-Polymer by the use of Borax

Abstract

Utilization of alternate materials like GGBS based Geo-polymer reduces the dependence on the energy intensive materials like OPC. However, the use of Geo-Polymers is limited despite many good features of it, due to the fast setting time which is generally less than 30 minutes in most of the cases,as a result, this wonderful material is limited to lab testing and still not acceptable in realtime usage. This research makes a genuine effort to increase the setting time by using a catalytic poison like Borax.
