Abstract:Concrete is a brittle material when subjected to design and accidental impact loads, which are expected along the life span of the structure. To improve the impact performance of concrete, steel fibers are used as short discrete material reinforcing elements. Among the available impact test, the ACI 544-2R repeated impact test is considered as the simplest and cheapest test procedure that needs no sophisticated sensors and costly techniques, which is used as a qualitative tool to evaluate the impact of fibrous… Show more
