Abstract：The rapid hardening concrete of sulfur aluminum cement base was modified by adding composite admixture and polypropylene fiber. The influence of composite admixture and polypropylene fiber on mechanical properties of the rapid hardening concrete was summarized. The results show that the optimal modification scheme is composite admixture of 10% and the polypropy-lene fiber content of 0.2%,the compressive strength and flexural strength at 4 h are 4.4% and 12.2% higher than those of the benchmark concrete respectively,and 28 d flexural strength increased by 19.2%.
