Abstract

A description is given of a modified instrumented Charpy test that is designed to enable impact-testing of cement-based composites. Problems encountered in instrumented impact testing of such composites and solutions to overcome them are discussed. Results of tests on concrete specimens at four different impact velocities are reported and are used to evaluate the performance of the test setup. A simple spring-mass model is used to verify the test results. This model is capable of providing suitable guidelines for the apriori selection of the basic test parameters with a view to minimize parasitic effects of inertial loading.
