This work conducted laboratory studies to assess the utilization of treated palm oil fuel ash to produce self-compacting concrete (SCC) in terms of its cost and sustainability. Two types of palm oil fuel ash namely treated palm oil fuel ash (T-POFA) and modified palm oil fuel ash (MT-POFA), were used as cement replacements. The SCC specimens were prepared with 0, 50, and 70 replacement (by mass) of OPC with T-POFA and MT-POA at a constant W/B ratio of 0.35. Fresh properties and compressive strength tests of SCC were performed and investigated. In addition, the cost and sustainability of SCC including high volumes of T-POFA and MT-POFA were assessed. The results demonstrate that replacing OPC with T-POFA and MT-POFA slightly improved the fresh properties of SCC as well as increased the compressive strength at later ages. In addition, the concrete specimens incorporated in 50 treated POFAs have significantly reduced carbon dioxide emissions (CO2) approximately 32 for SCC with 50 T-POFA and 41 for SCC with 50 MT-POFA as well as lowered costs. The results suggest that T-POFA and MT-POFA can be successfully used as cement substitutions up to 70 to develop sustainable and cost-effective concrete. © International Journal of Sustainable Building Technology and Urban Development.
