Abstract: 
Cementitious materials can be subjected to dynamic loading for variety of reasons. Due to the inherent brittleness and low tensile strength of most cement-based elements, such impact loadings can cause severe damage, resulting in extensive cracking. To date dynamic properties of cement composites have been studied mainly for short fibers composites. The research to date clearly demonstrates a significant improvement in the energy absorption capacity of fabric reinforced cement composites under static loading as compared to plain concrete materials and other fiber cement composites. The aim of this work was to study the dynamic behavior of textile-cement based composites. A pendulum impact set up was used to study the impact behavior of the cement composites. Composites with different fabrics were examined made from AR glass with two different mesh sizes, polyethylene and carbon. Also, specimens made from short AR glass fibers were studied for comparison. The benefit of using fabrics as reinforcements for cement-based elements exposed to dynamic loading was clearly demonstrated in this study. Composites reinforced with fabrics were shown significantly grater impact behavior compared to those reinforced with short fibers. The best impact strength was obtained of composite reinforced with carbon fabric.
