    Abstract

    The present paper investigates the tensile stress-strain behaviour of a cementitious composite at different strain rates ranging from 10-4 s-1 up to 0.05 s-1. The cementitious composite exists of an inorganic phosphate cement (IPC) matrix reinforced with 20 vol% of different unidirectional fibre types. The results indicate that the use of statically determined material data for dynamic or impact loading on structural components can not be recommended for these kinds of materials. Depending on the used fibre type the material is sensitive to strain rate. Effects of strain rate were found on the multiple cracking and post-cracking behaviour.
