Study On Application Of The Epoxy Mortar In A Large Scale

There are a large number of concrete buildings in the irrigation works of our country. For various kinds of reasons, they have the destruction phenomenon, for example, aging disease, erode and wear etc, which influence the productivity effect and safe operation of the key irrigation works. The damage positions must adopt performance superior material and reasonable construction in building repair.This paper has introduced good repair result of the epoxy mortar through the instance of mending the damaged concrete project, and pointed out that the epoxy mortar has wide prospects of mending irrigation works and resisting structure eroded. Because of the development of the raw materials market, the various kinds of epoxy mortar can be developed according to different project demands.At present, the main destruction phenomenons that epoxy mortar used in a large scale include aging, crazing, disengaging etc. The elasticity epoxy mortar has advantage in resisting crazing and disengaging and can substitute the existing epoxy, especially in open-air environment. Though adjusting proportion of material and improving construction craft, it could be applied in various kinds of project mended and the structure resisting eroded, so it has wide prospects.The ordinary epoxy mortar layer of Xin'anjiang has operated for 40 years. Its course and phenomenon are representative in destruction of the epoxy mortar. The paper combined investigation result of the state of epoxy mortar in Xin'anjiang with structure model of thin layer to analyze the course of destruction and influence factors, and pointed out the advantage of the elasticity epoxy mortar, which have superiormaterial performance.In order to test the actual state of using the elasticity epoxy mortar in a large scale, the construction test was operated on the surface of the flooding dam. Some construction questions had been detected in the two former tests. According to the result of the locale investigation and experiments, origin of the problem is found. Then the third test succeed.The innovation of the paper exists in combining investigation result of the state of epoxy mortar of Xin'anjiang with structure model of thin layer and ultimate deformation of material to analyze production and evolution of the crack of the epoxy mortar and to discuss influence factor that the crack produces, and pointing out the using advantage of the elasticity epoxy mortar. At the same time, the construction questions of the elasticity epoxy mortar are detected through observation and experiments and the origin of the questions have been found. The questions are solved by adjusting material and the way of construction.
