Prediction of ultimate strength of reinforced geopolymer concrete wall panels in one-way action

An experimental investigation has been carried out to study the strength and behaviour of Ordinary Portland cement concrete (OPC) and geopolymer concrete (GPC) wall panels. A total of 20 wall panels were tested under uniformly distributed axial load in one-way in-plane action. Out of these, 10 wall panels were made of OPC and the remaining was of GPC. The main variables considered in this study were slenderness ratio (SR) and aspect ratio (AR) of the walls. Also a method was proposed to predict the ultimate load of reinforced GPC wall panels.
