桥梁混凝土工程的开裂问题、耐久性的问题一直是桥梁混凝土材料研究领域中的热点,而各种开裂是导致目前桥梁混凝土结构耐久性差的主要原因。目前,桥梁混凝土裂缝的修补方法有多种,现研究的对象是一种以低粘度环氧树脂为基料,添加稀释剂、固化剂等助剂,制备的新型的低粘度环氧结构胶——渗透型结构胶。这种结构胶适用于桥梁、道路、港口、房屋、工业厂房等结构的加固修复,可提高结构强度和耐久性。
The problem of cracking and durability of bridge concrete engineering has always been a hot topic in the field of bridge concrete materials research, and various cracking is the main reason of the poor durability of bridge concrete structures. At present, there are many ways to repair concrete cracks in bridges. The research object of this paper is a new type of low viscosity epoxy structural adhesive with low viscosity epoxy resin as base material, diluent and curing agent, - Permeable structural adhesive. This structure of plastic for bridges, roads, ports, houses, industrial plants and other structures to strengthen the repair, can improve the structural strength and durability.
