| Abstract | ||
| The aim of this study is to find the effect of water to powder ratio on some of the mechanical properties of self-compacting concrete (SCC) made from locally available materials. To determine the workability, different test methods are adopted in this research such as slump-flow, T50 slump-flow, L-box, U-box and V-funnel. The mechanical properties studied are compressive strength, splitting tensile strength, flexural strength and static modulus of elasticity. Two non-destructive test methods, ultra-sonic pulse velocity and Schmidt rebound hammer test are tested also. Based on the results of this work, it is possible to produce SCC from locally available materials that satisfy the requirements of this type of concrete. It can be stated that SCC produced is sensitive to water to powder ratio. The results obtained from this study indicate that increasing W/P ratio from (40-62) % decreases the compressive strength by 23 %, splitting tensile strength by 20 %, flexural strength by 46 %, static modulus of elasticity by 9 %, ultra-sonic pulse velocity by 13 % and rebound number by 15%. | ||
