1
Effects of polypropylene fiber (PPF) on properties of phosphate cement-based concrete, such as flowability, operable time, flexural and compressive strength were investigated.
主要研究了聚丙烯纤维(PPF)对磷酸盐混凝土性能如流动性、可操作时间、抗折和抗压强度的影响。

Mixture proportions, flowability, crack propagation at early ages, strength, shrinkage, carbonation and the freezing and thawing resistance of flowing concrete with high flowability were investigated.
The polypropylene fibre have the better effect to concrete that the flowability is not too big than that is big. The polyacrylonitrile have no use to improve the homogeneity ofconcrete.
