The use of supplementary cementitious materials (SCMs) in Self-compacting concrete (SCC) is becoming popular in civil engineering research and developments. This is mostly due to the enhanced rheological characteristics and economic benefits influenced by the inclusion of these SCMs in SCC works. This study experimentally investigated the flexural performance and deformation characteristics of self-compacting concrete (SCC) containing corn-cob ash (CCA). A total of twelve SCC mixes were investigated - eight mixes of CCA blended SCC containing admixtures and two non-CCA blended-SCC mixes with and without admixtures were studied and flexural behavior of 150 × 150 × 600 mm reinforced concrete beam specimens investigated. Although, the control SCC had higher ultimate failure load than the CCA blended SCC, failure loads of all the mixes increased with increased water-binder ratio and CCA blended SCC had better durability properties in first crack development than the control SCC, and their flexural stiffness reduced with increased CCA content. All tested beam specimen failed in shear.
