The challenge of utilisation of sustainable, durable and cost effective building materials leads civil engineering researcher in rich agro-industrial country such as Malaysia to find suitable building materials alternatives. This paper illustrates the aspect of sustainability of cellular lightweight concrete composed of POFA and PFA at the percentage of 30% and 20% respectively when exposed to sulphuric acid for duarability test.The mix of POFA and PFA used on weight replacement of cement and concrete OPC perforemance considered as a control sample taken in this research. All samples were subjected to the curing in water for 28 days before the immersion in sulphuric acid having with a pH value of 1 to 2160 hours. The progressive deterioration was evaluated by the change in mass of the samples and visual inspection decisions regarding the compressive strength. The study showed that 30% POFA and 20% PFA improves the strength of aerated concrete attack by sulphuric acid.References
