改性聚丙烯纤维混凝土性能的试验研究

TEST AND RESEARCH ON PERFORMANCE OF MODIFIED POLYPROPYLENE FIBER CONCRETE

在混凝土原材料中添加改性聚丙烯纤维,然后对试件进行混凝土性能试验,结果表明,改性聚丙烯纤维不仅可改善混凝土强度,降低混凝土早期干燥收缩率,而且还可使纤维混凝土的抗裂、抗冲击及耐久性方面均高于普通混凝土。

Test of concrete performance is carried out by adding modified polypropylene fiber into raw materials of concrete. The test result indicates that modified polypropylene fiber can not only improve concrete strength, but also reduce drying shrinkage of concrete at early period. Modified polypropylene fiber concrete has better crack resistance, shock resistance and durability than ordinary concrete.
