Abstract

This study furnishes the properties of a binary blended Geopolymer concrete that is prepared by using industrial waste exhausts i.e., fly ash and GGBS as source materials at a proportion of (50%+50%). An experimental study was carried out in two phases. In phase I, an effort was made to produce binary blended Geopolymer concrete with different molarity concentrations of NaOH ranging from 8-16 M with an increment of 2 M concentration and the compressive strength of normal (M30) and high strength (M70) grade GPC is studied for a period of 1,3,7,14 and 28 days of ambient curing. The test results revealed that the compressive strength increases with increase in molarity concentration up to 12M. In the second phase of study, the mechanical characteristics of binary blended GPC are studied and reported. An equation was proposed to determine the compressive strength based on the molarity concentration of NaOH.
