摘要
聚乙烯醇纤维混凝土是一种新型复合材料,具有良好的抗拉、抗弯、耐冲击、抗疲劳和高韧性等优点,已广泛应用于梁体桥面,结合西部山区铁路大型枢纽建设项目,配制掺量不同的聚乙烯醇纤维混凝土,对其基本力学性能进行试验,并与普通混凝土进行对比。
Polyvinyl alcohol fiber reinforced concrete is a new composite material,which has the advantages of good tensile strength,bending resistance,impact resistance,fatigue resistance and high toughness.It has been widely used in the beam deck.Combined with the large-scale railway hub construction project in western mountainous areas,polyvinyl alcohol fiber reinforced concrete with different content is prepared.Its basic mechanical properties are tested and compared with ordinary concrete.
