Abstract

In this paper the effect of concrete aging on contact force and contact time during the impact of steel ball upon a concrete beam has been investigated. Three concrete beams were tested at the ages of 7, 14, 28, 56, 91 and 182 days. It was found that contact force increases with concrete age, whereas the contact duration becomes shorter. The most significant changes occur at early ages, before 28 days, and this process slows down after this age: average maximum contact force is increased by 19.82% and average contact time is decreased by 20.87%. This is related to concrete hardening: at very early ages concrete behaves more like a viscoelastic material and possesses a certain damping effect which is reduced with concrete aging.
