Abstract

Several test methods used for impact tests of fiber reinforced concrete (FRC) are reviewed in the article with a view to evaluate the reliability of the material responses obtained therefrom. Parasitic effects of inertia observed while conducting instrumented impact tests on concrete composites are discussed at length. Based on experience gained during the course of the development of a modified instrumented Charpy test scheme, useful guidelines for selection of the various test parameters are proposed in order to minimize parasitic inertial loads. The effect of strain-rate on the flexural behavior of unreinforced matrix and 3 different fiber reinforced concrete (FRC) mixes are discussed. Results obtained from the modified instrumented Charpy tests on cement composites compare well with results from several similar investigations that use an instrumented drop-weight set-up.
