Abstract To study the effect of loading rate on the fracture properties of high-performance cement-based composites (HPCC), three-point bending tests were carried out on HPCC using notched rectangular beams. The crack mouth opening displacement (CMOD) was used as the loa-ding control parameter. The loading rates were 0.001 mm/s, 0.01 mm/s and 0.1 mm/s respectively, and the volume fraction of steel fiber was 0% and 2%.A series of fracture characteristic parameters such as first crack stress, elastic modulus, bending strength, unstable fracture toughness and fracture energy were analyzed based on the P-CMOD curves. The experiment results show that: (i) the first crack stress and elastic modulus are almost independent of the steel fiber content and loading rate; (ii) the bending strength of HPCC is logarithmically related to the strain rate ratio, and the bending strength of HPCC with steel fiber is more sensitive to the loading rate; (iii) the unstable fracture toughness and fracture energy of HPCC with steel fiber are greatly improved, but the sensitivity to loading rate is relatively low. Steel fiber can effectively improve the ability of HPCC material to resist impact load.

Key words： high-performance cement-based composites (HPCC) steel fiber fracture loading rate P-CMOD
