研究成果和工程经验证明,聚丙烯纤维能减少和防止混凝土在塑性和初期硬化阶段的收缩裂缝产生,从而提高防渗、抗冻、抗冲磨等性能。本文介绍聚丙烯纤维混凝土的性能和在水利水电工程中广泛的应用前景。
The research results and engineering experience prove that polypropylene fiber can reduce and prevent concrete from shrinking and cracking in the plasticity and initial stage of hardening, so as to improve the anti-seepage, anti-freezing and anti-abrasion properties. This paper introduces the properties of polypropylene fiber concrete and its wide application in water conservancy and hydropower projects.
