Abstract

In order to reveal the effect of different interface treatment processes on the bonding properties of low shrinkage and high viscosity multi-element composite repair mortar (LSHVRM) to the repaired concrete workpiece, 54 repair test-pieces were designed. The effect of treatment processes, such as brushing migration corrosion inhibitor, spraying DPS reinforcing agent, brushing migration corrosion inhibitor and chemical conversion of corrosion products on steel bar on the anti-stripping performance of the repaired workpieces were studied especially, focusing on the influence of carbonization degree of concrete interface at the site to be repaired and whether there are steel bars buried or not. The results show that the carbonization degree of the surface of the repairing concrete has only a little effect on the bonding performance, namely the surface brushing migration type rust inhibitor resulted in an effect range between -1.4% and 6.8%. The spraying DPS reinforcing agent resulted in an increase range of 2.7%-7.4%. In case, rust steel bars emerged at the interface, the effect of steel brush treatment brought an effect range of -2.7% to 5.4%. However, The combination of spraying DPS reinforcing agent and brushing migration corrosion inhibitor could increase the bonding performance within a range of 0.6% and 6.9%. The spraying DPS reinforcing agent after the treatment with chemical conversion agent for rust steel bars could provide an increasing effect within a range of 4.5% and 16.6%. In general, the interface treatment process, such as steel brush treatment of steel bar, brush migration corrosion inhibitor and chemical conversion treatment of the rust steel bar, will bring little adverse effect on the bonding performance of the repaired concrete, while bring improvement effect within a small range, although these treatment methods has induced different degrees of carburization for the surface of repairing concrete.

Key words: low shrinkage and high viscosity multiple composite repair mortar interface treatment process transformation of corroded steel bar migrating rust inhibitor bonding performance
