钢—聚丙烯混杂纤维混凝土抗冲击强度研究

Shock strength research of the steel-polypropylene hybrid fiber concrete

在分析掺加单一纤维混凝土优缺点的基础上,以提高混凝土结构抗冲击性和耐久性为目的,提出了适量钢纤维(S)—聚丙烯纤维(P)增强混凝土的设想,并给出了试验所用的配合比,在对S—P混杂纤维混凝土进行抗冲击强度试验分析后,得出混杂纤维对混凝土起到了优势叠加效果的结论。

Based on the merits and faults analysis of adding single fiber concrete,and in order to increase the shock resistance and endurance of the concrete structure,it brings forward the assumption of strengthening concrete by proper steel fiber-polypropylene fiber and the adaptation ratio in the test.After the shock strength test analysis of the S-P hybrid fiber concrete,it gets the conclusion of directional preponderance effect by adding the hybrid fiber to concrete.
