Experimental Investigation on Bond Strength Properties of Geopolymer Concrete

Abstract

Geopolymers are new alternative binders for the development of concrete. Geopolymer concrete can overcome the environmental impact of cement concrete. Highlight of the work is development of geopolymer concrete from industrial by-products such as Ground Granulated Blast Furnace Slag (GGBS) and dolomite. Performance of structural elements mostly depends on the bond between concrete and reinforcement. Enhanced bond stress was observed in geopolymer concrete than that of cement concrete. Different equations were evaluated for the prediction of bond stress. Effects of addition of different percentage of dolomite on bond strength are also investigated. Addition of GGBS and dolomite can reduce the production cost of concrete and can also reduce its disposal problem.
