摘要

Fly ash based Geopolymer concrete (GPC) is an environment friendly alternative to conventional concrete made from alkali activated aluminosilicate and aggregate. This study intends to examine the effects of confinement on the behaviour of GPC and conventional Portland Cement Concrete (PCC). Out of the 36 cylinders tested under monotonic loading 24 cylinders were made with GPC and the remaining with PCC. The variable considered in this study is the volumetric ratio of confinement. An analytical model is proposed for the stress-strain behaviour of confined GPC. The results showed that confinement reinforcement greatly improved the strength and ductility of GPC than PCC.
