Research on Anti-abrasion Property of Waterborne Epoxy Mortar Based on Underwater Steel Ball Method

Abstract

Waterborne epoxy emulsion modified mortar has been paid more and more attention and applied in the field of hydraulic construction. Its physical and mechanical properties, especially the anti-erosion properties, are the key influencing parameters applied to the drainage structures such as sand tunnel and spillway dam surface. A high-speed underwater steel ball punching tester was used to simulate the impact of pushing mass on the abrasion resistance of water-borne epoxy mortar. In this paper, the abrasion resistance of mortar under different rotational speeds and different grades of grinding steel balls are analyzed, and the test parameters of underwater steel ball method suitable for waterborne epoxy mortar are explored, then a method for predicting the punching and grinding life of mortar is well proposed. The research results provide a basis for the application of water-borne epoxy mortar to hydraulic structures required by anti-impact abrasion.
