The least well known loading type is the impact loading that are affecting on to RC structures. For these reason an experimental study is conducted, and the effect of concrete compression strength variation on impact behavior of concrete investigated. Total ten beam specimens at which five of them are manufactured with normal compression strength concrete without reinforcement are prepared. Remaining five had high concrete compression strength. These specimens are tested under the impact loading that is applied by dropping constant weight hammer from five different heights. The acceleration due to impact loading is measured against time. The change of velocity, displacement and energy are calculated for all specimens. The failure modes of the specimens with normal and high concrete compression strength are observed under the loading of constant weight impact hammer that are dropped from different heights. The increase in compression strength of concrete is significantly affected on the impact behaviors of the specimen, and as the compression strength increase impact behavior improved. Dissipated energy, the number of the hammer drops, and accelerations are increased, and displacement is dropped.
