钢纤维和聚丙烯纤维混凝土配合比试验研究

Experimental Study on Design Mix of Steel and Polypropylene Fiber Concrete

文章根据长江口深水航道治理工程大圆筒结构对钢纤维和聚丙烯纤维混凝土的强度要求,进行了大量的室内纤维混凝土配合比试验和现场纤维混凝土配制试验,得出了满足设计要求的纤维混凝土配合比,并经实际施工证明是成功的。

Based on the strength requirements of the steel and polypropylene fiber concrete in the large diameter cylinders used on the regulation project for the deep water navigational channels in the Yangtze River, a lot of laboratory tests as well as field tests were made on the design mix proportions for the fiber concrete, from which mix proportions meeting the design requirement were obtained. The mix proportions proved to be successful after being actually used on the project.
