▎ 摘　　要

NOVELTY - High-adhesion concrete interface bonding, comprises (i) chiseling the old concrete surface and removing surface ash, mortar or other stains, (ii) uniformly spraying G/GO dispersion on old concrete surface obtained in step (i) to obtain pre-bonding surface, the 0.01-100 mg/l G/GO dispersion liquid includes single-layer graphene, multi-layer graphene, few-layer graphene, industrial grade graphene oxide, single-layer stone graphene oxide, and/or multi-layer graphene oxide, the 0.001 mg/l G/GO dispersant includes sodium dodecyl benzene sulfonate, sodium dodecylbenzene sulfate, polyacrylic acid polymer, cetyltrimethylammonium bromide, calcium lignosulfonate, gum arabic powder, and/or methyl orange, and the dispersion medium is water, and (iii) drying the pretreatment interface, covering the bonding mortar on pretreated bonding surface of old concrete, tightly bonding the old concrete with bonding mortar layer, and curing the bonding mortar. USE - The method is useful for high-adhesion concrete interface bonding. ADVANTAGE - The method: overcomes the disadvantages of the conventional G/GO doped mortar dispersing difficulty; is simple and easy; utilizes little G/GO dosage; has excellent economical efficiency; does not need to consider the problem of uneven dispersion; and improves the bonding force between bonding mortar and concrete interface.
