摘要
基于聚丙烯纤维(PPF)是一种轻质热塑性纤维,具有微小的直径、低密度、低弹性模量,且无吸水性,因此,聚丙烯纤维混凝土通常表现出优良的和易性、力学特性、抗裂特性及抗渗特性。这使得它能有效地解决水利水电工程中的混凝土渗透和开裂问题。研究将聚丙烯纤维作为增强相添加至混凝土体系中,探究不同聚丙烯纤维掺杂量对混凝土和易性、密度、力学强度和杨氏模量的影响规律,以制备出性能最佳的聚丙烯纤维增强混凝土,并在水利水电工程中得到广泛的应用。
polypropylene fiber(PPF)is a lightweight thermoplastic fiber with a small diameter,low density,low elastic modulus,and no water absorption.Therefore,polypropylene fiber concrete usually exhibits excellent workability,mechanical properties,crack resistance,and impermeability.This makes it an effective material to solve the problem of concrete penetration and cracking in hydraulic and hydroelectric engineering.Polypropylene fiber was added to concrete system as reinforcement phase,and the influence law of different polypropylene fiber doping amount on concrete workability,density,mechanical strength and Young’s modulus was studied to prepare polypropylene fiber reinforced concrete with the best performance,and it was widely used in hydraulic and hydroelectric engineering.
