摘要：

In this paper, the investigation of the compressive behaviour of lightweight oil palm shell concrete (OPSC) containing ground granulated blast furnace slag (GGBS) was carried out. The variables studied include the compressive strength class (grade 25, 35 and 45), curing method (air and water curing) and GGBS replacement level (20% and 60%). Higher GGBS content and air curing resulted in lower mechanical properties such as compressive strength and modulus of elasticity (MOE) of the concrete. Analysis revealed that when the experimental stress-strain parameters such as the peak stress, strain at peak stress and MOE were incorporated into Popovics stress-strain model, the compressive stress-strain relationship of the lightweight concrete could be well-estimated.
