Mechanical Strength and Resistance to Ultraviolet Radiation of Repairing Mortars Based on Epoxy Resin

Abstract:

The epoxy resin based repairing material(REM) is suitable for repairing cracks and holes in concrete or broken concrete due to its high bond strength and high durability. The compressive strength and flexile strength are 76.4MPa and ＞12.5MPa at 28d, and the retest strength still remain 73.4MPa and ＞12.5MPa respectively. The fracture location of cement mortar specimen bonded by RME is at cement mortar, that is, the bond strength between REM and cement mortar is more than mortar itself. The compressive strength of RME keeps 93.3% under ultraviolet light radiation (Peak Value 308nm, 49.5 W/m²) for 1700h.
