Self-compacting concrete was introduced to the construction industries in early 1990's to cater problem regarding the durability of structural concrete. It was indicated in literature that much of the extensive research and development work has been concerned with the achievement and assessment of fresh properties. However, the hardened properties that are of paramount interest to structural designers and users. Pulverized fuel ash was used as additives in this project due to their capability of imparting considerable physical and economics benefits of concrete. This research study was initiated with the aim to study the modulus of elasticity and modulus of rupture of self-compacting concrete that incorporating pulverized fuel ash since these modulus are fundamental parameters necessary in structural analysis, especially when the design is based on elasticity consideration. Split cylinder and prism flexure test were used to determine the modulus study. The effects of variable water to binder ratio together with variable PF A content were examined. The value used in mix design was within the optimum value given in literatures found. Experimental results indicated that the modulus of rupture has shown no significant pattern with regard to water to binder ratio. The modulus of elasticity also has exhibited the same pattern where there is no significant increment with increasing pulverized fuel ash content.
