Abstract

Geopolymer concrete (GPC), also termed as Alkali activated material is an innovative and green concrete, serving as an alternative to the ordinary Portland cement (OPC) concrete. This study aims to investigate the flexural behavior of geopolymer concrete to better understand the mechanical properties and potential application in structural engineering. This research involves the formulation of geopolymer mixes using various binder compositions, incorporating different types of aggregates, and curing at ambient conditions. The experimental program includes 3-point bending tests on the prismatic geopolymer specimens to evaluate their flexural strength, load-CMOD, and cracking behavior. Additionally, the effect of GGBFS content in GPC has been studied. The results of the study revealed that geopolymer concrete exhibits considerable flexural strength comparable to the OPC concrete.
