Instrumented impact tests have been in use since the early eighties for studying the fracture characteristics of cement-based composites at high rates of loading. While significant progress has been made during the last decade in perfecting such tests and in deducing the material response from such tests, careful interpretation of the parasitic effects still pose numerous challenges. These challenges are discussed here alongside a summary of results from several previous investigations. Preliminary results from this investigation are also presented and discussed.
