摘要
Abstract
Fire-resistant coating for tunnel can improve the fire resistance of the tunnel structure,but when the bond strength between coating and lining is low,it will cause fall off,which will affect the fire prevention effect.The relationship between moisture,curing humidity,curing temperature and bond strength was studied by tensile test.The study results show that the humidity degree of lining has important influence on bond performance,The higher humidity of lining results from lower bond performance.Curing humidity helps to improve the bond strength.When curing temperature is low,bond strength increases with the increases of curing temperature,but bond strength decreases when the curing temperature is higher.The research results can provide technical support for the application of ire-resistant coating for tunnel,and has good theoretical and practical significance.关键词
