摘要
综述目前高强混凝土的抗火灾高温性能的研究进展,并对聚丙烯纤维、橡胶粉、钢纤维等对改善高强混凝土的高温性能情况进行比较,指出研究中所存在的问题和今后的研究发展方向,对高强混凝土的高温性能研究和应用起到指导作用。
High-strength concrete has good mechanical properties and durability, however, in the fire, that damage occurred easily becomes the stumbling block to high-strength concrete used widely.Mixing polypropylene fiber with the high-strength concrete to improve the performance in high-temperature fire become a hot research field.The high-strength concrete mixed with appropriate rubber powder whose surface has been modified could improve the toughness and brittle to implement the performance of resistant high-temperature fire, at the same time, it could solve the problem of waste rubber.The recent researches in the fire resistance high-strength concrete are expounded.
