改性聚丙烯纤维长度、掺量对混凝土性能影响的试验研究

Experimental research on effect of mixed amount and length of hydrophilic polypropylene fiber on concrete property

介绍了亲水性聚丙烯纤维的掺量及长度对普通混凝土力学特性的影响情况.通过试验表明,掺入聚丙烯纤维可使普通混凝土的抗压强度、劈裂抗拉强度、抗收缩、抗冻融等性能有所改善.

Effect of mixed hydrophilic polypropylene fiber amount and length on plain concrete mechanics property is introduced.Test shows that the behaviors of compressive strength,split tensile strength,shrinkage and freeze-thaw resistance of plain concrete with polypropylene fiber are improved.
