【Abstract】 This article introduces the erosion and abrasion of hydraulic structures and the affection of toughness epoxy resin resistance to erosion and abrasion of the concrete. The mechanism of resistance to erosion and abrasion of "sea island structure" epoxy resin mortar is discussed in detail. The result of the resistance to erosion and abrasion experimentation shows that the resistance to erosion and abrasion of "sea island structure" epoxy resin mortar is better than common epoxy resin mortar and C70 concrete. The analysis of the scanning electron microscope pictures indicates the existence of "sea island structure" in the epoxy resin that is the key to improve rupture toughness of the epoxy resin. The application of the materials and the construction methods are also discussed.更多还原
