摘要
围绕钢纤维-聚丙烯腈纤维混杂增强混凝土进行了系统研究,研究了纤维的混杂方式对断裂性能的影响,在试验的基础上,得到了表征材料断裂性能的断裂韧度KIC和断裂能GF。
In this paper the mechanic properties of the concrete reinforced with the micro-steel fibers and polypropylene were studied systematically. The influence of the hybrid way on the fracture properties was studied. Based on the experiment results, the fracture ductility index Ktc and the fracture energy GF were obtained for the hybrid reinforced concrete.
