摘要
主要研究了道路快速修补钢纤混凝土、高性能水泥砂浆及混凝土道面快速修补料的力学性能及其与旧混凝土的粘结性能,并在京珠高速进行试验,全面检验桥梁病害维修新材料新技术的实际应用效果,对今后桥梁结构物加固维修有很好的借鉴意义.
The paper studies the mechanical properties of three kinds of materials：rapid repair of steel fiber concrete road,high performance mortar and rapid repair of concrete pavement materials,and their bonding properties with the old concrete.In Beijing-Zhuhai Expressway,three materials were used to bridge defects in maintenance in order to test the practical application of new materials.This is reinforced in the future maintenance of the bridge structure has a good reference.
