改性聚丙烯对混凝土性能影响的研究及应用

Research on modified polypropylene influence performance of the concrete and its application

本文研究了一种新型的合成纤维——多微孔型的改性聚丙烯纤维在混凝土中的掺加工艺及应用效果。实验表明,改性聚丙烯纤维掺加在混凝土中可以减少混凝土的裂纹,使混凝土表面光滑,提高混凝土的抗裂性、抗渗性和抗冻性,且对工程施工没有特殊要求。

This article introduces one kind of new synthetic fiber-multi-pore modified polypropylene fiber mix in with the concrete. The experiment results indicate that, the modified polypropylene fiber mix in with the concrete may reduce crack of the concrete, causes the concrete surface to be smooth, enhances the crack resistance, the impermeability and the freeze resistance of the concrete, and also does not have the special request to the project construction.
