Influence of cationic epoxy resin type on electrophoretic deposition effect on repair of rust-cracked reinforced concrete
Highlights Use electrophoretic deposition method to repair rust-cracked reinforced concrete. After Electrophoretic deposition repair, the carbonation resistance and waterproofing performance of the specimens significantly improved. The carbonation resistance and waterproofing performance of repaired reinforced concrete are mainly affected by the film density of epoxy resin. The higher the molecular weight of the cationic epoxy resin in the repair solution, the lower the crack filling depth and film forming compactness of epoxy resin.
Abstract This study proposed an electrophoretic deposition repair method to effectively repair and improve the durability of rust-cracked reinforced concrete structures, exploring the influence of cationic epoxy resin types on the repair process. After electrophoretic deposition repair, the carbonation resistance and waterproofing performance of the specimens improved significantly; as the repair in the solution of cationic epoxy resin molecular weight increased, the specimen surface crack healing rate and deposition rate increased; the larger the molecular weight of the cationic epoxy resin in the repair solution, the poorer the compactness of the repaired specimen, and the smaller the filling depth of epoxy resin.
