Background
the water-based epoxy resin mortar is a composite material for improving the comprehensive performance of mortar by adding water-based epoxy resin and a water-based epoxy curing agent into common cement mortar, and is commonly used for repairing a building concrete structure, particularly for repairing scouring, abrasion and cavitation damage of a hydraulic concrete building.
Scouring, abrasion and cavitation erosion or the combined action of the scouring, the abrasion and the cavitation erosion are one of common damage reasons of hydraulic outlet buildings, and 70% of reservoir outlet buildings in China have scouring abrasion and cavitation erosion damage. Especially under the action of high-speed sand-containing water flow, the scouring abrasion and cavitation erosion of a hydraulic water outlet structure are faster and deeper. Therefore, the reinforcement and reinforcement of the structure of the old dam water outlet building and the anti-abrasion protection of the high dam water outlet building are also difficult points for the research of engineering researchers. The epoxy resin has the advantages of excellent mechanical property, low curing shrinkage, good adhesion with a base material and the like, and is used as a cementing material and an aggregate to prepare epoxy mortar for the surface abrasion protection of hydraulic water release buildings for over 40 years.
At present, the common method for testing the abrasion resistance of the epoxy mortar is an underwater steel ball method.
