Abstract

Self-Compacting Concrete (SCC) has been used widely nowadays and it is more prone to plastic and drying shrinkage cracks. Under impact loading, the micro-cracks present in the concrete may propagate, widen and lead to failure of concrete structures. Researches on Fibre Reinforced Concrete (FRC) has been proven to be effective in improving the impact strength of concrete. So, in this study, an attempt has been made to study the behaviour of Quaternary Blended Self-Compacting Concrete (QBSCC) under impact, with crimped steel fibres. The binder comprises of 40% cement, 10% microsilica, 25% flyash, and 25% GGBFS. Two w/b ratios of 0.3 and 0.4 with super-plasticiser of 1.8% and 1.6% by weight of binder, respectively were used. Crimped steel fibre content of 0, 0.5, 1, 1.5% by weight of binder was used. The impact strength in terms of number of blows were determined using pendulum type impact testing machine for QBSCC beams at 28, 90, and 180 days. QBSCC with crimped steel fibres exhibited better impact resistance than reference concrete without steel. Also, impact strength of QBSCC increased as percentage of steel fibres increased. Maximum impact strength of QBSCC was obtained with 1.5% of steel fibres.
