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.
研究了具有高流动性的流态混凝土的配比、流动性、早期裂纹扩展、强度、收缩、碳化和抗冻融性，这种混凝土无论在成本上还是性能上都是非常可行的。
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 of concrete.
聚丙烯纤维不适于大流动性混凝土，对中小流动性的混凝土匀质性改善作用大，聚丙烯腈不宜用于匀质性的改善。
