Investigation of the effect on impact strength of the concrete of aggregate type

The properties of aggregate cement dosage and water content which are used in concrete mixture are most important factors as affecting the strength of concrete. Even if there was known how these factors affect the tensile strength and pressure, the impact resistance is not fully understood.In this study, the effects of impact resistance on aggregate type and the dosage of cement. For this purpose, some samples are prepared with the normal, light weight, and mixed (normal + light weight) aggregates with 300 and 450 doses mixtures.As expected in charpy impact test, the highest resistance were determined in 450 doses aggregate concrete and the lowest resistance were determined in 300 doses aggregate concrete on the samples under pressure and flexural strength. But some fluctuations.were observed after looking at the ratio of impact strength to tensile strength.
