Abstract

This research aim to study the Influence of mix proportions on the impact resistance of high strength concrete, Trial laboratory batches were used including as follows: -Normal concrete mixture (C1) as a reference mix ((w/c) = 0.45, without admixtures);-Four concrete mixtures (C2, C3, C4, C5) prepared by fixing (w/c) =0.45, and using different amount of super plasticizers (0.25, 0.50, 0.75, 1.00)% as a percentage of cement content, respectively; -Four concrete mixtures (C6, C7, C8, C9) prepared by reducing and fixing (w/c) = 0.30, and using silica fume = (15)% as replacement of cement content and different amount of superplasticizers (1.25, 1.50, 1.75, 2.00)% as a percentage of cement content; and -Three concrete mixtures (C10, C11, C12) prepared by fixing the amount of superplasticizers (1.50)% and using different (w/c) = (0.40, 0.29, 0.27).Results show that Mixture C11 prepared with (1.50%) addition of superplasticizers and (15%) addition of silica fume leads to (90.29%) increasing in the compressive strength and records an improvement in the impact resistance by (725.56%) as compared with the reference mix. On the other hand, all of the mix proportions lead to an increase in both compressive strength and impact resistance for all the mixes.
