The invention provides an epoxy resin concrete for grouting bridge expansion joints and road-bridge junctions. The composition of the epoxy resin concrete includes the following raw materials in parts by weight: 70-80 parts of bisphenol A epoxy resin E51, epoxy Active toughening agent D-411 5-10 parts, glycidyl ether 5-10 parts, defoamer 0.1-0.3 parts, leveling agent 0.1-0.3 parts, coupling agent 0.1-0.3 parts, Mannisamine 20-30 parts 50-60 parts of modified aromatic amine, 40-50 parts of polyamide, 10-20 parts of 425# cement, 10-20 parts of 10-20 mesh quartz sand, 40-50 parts of 8-10 mesh quartz sand, 5- 30-40 parts of 8 mesh quartz sand, 10-20 parts of polyarylether nitrile, 5-10 parts of sorbitol ester, 5-10 parts of polyoxyethylene sorbitol ester, 5-10 parts of 10-20 mesh glass bead powder. The present invention modifies the epoxy resin and the curing agent without adding any volatile solvent, so it has low requirements on the moisture content of the sand and gravel, and is easy to operate in the construction process, without heating, non-toxic and tasteless, and has high requirements on the quality of the construction personnel. Low temperature, low requirement for construction environment temperature, easy operation, performance far exceeds the existing on-site epoxy resin concrete.
