A research has been undertaken to study the effects, on the workability, compressive strength and shrinkage of foamed concrete by replacing up to 60% of the cement with Pulverized Fly Ash (PFA). This paper reports some recent findings on the densities, workability, shrinkage and compressive strength development of foamed concrete. Preformed foam by using local LCM foaming agent and foam generator were used to produce the foamed concrete. A total of fourteen types of mixtures with varying PFA content, water/binder ratio and foam/binder ratio were prepared and tested. The foamed concrete specimens were subjected to air-curing. Test results show that the optimum PFA content for maximum strength at 28 days is around 20% to 30%. Workability and drying shrinkage increase as the PFA replacement of cement increases.
