Graphene mortar for concrete maintenance paint of preventing neutralization and maintenance method of concrete

摘要

The present invention provides a graphene mortar for concrete repair, a paint for neutralization prevention, and a repair construction method using the same, comprising: arranging the damaged part of the concrete at the rear of the bridge expansion joint; And, a washing step of washing the cleaned damaged area; And, applying a rust preventive agent to the surface of the reinforcing bar in order to prevent oxidation of the reinforcing bar when exposed; and, a concrete adhesion strengthening agent application step of applying an adhesion strengthening agent to the surface of the damaged area; And, a cross-section restoration step of filling the damaged area by filling the mortar on the adhesion reinforcing agent of the damaged area; and curing the damaged area at a constant temperature after the cross-section restoration step; And, applying a functional paint having abrasion resistance to the cured surface and finishing it; using the mortar composition of the present invention to improve bonding with the damaged part of the structure, and using the paint composition to improve the abrasion resistance and resistance It is possible to improve mechanical properties by making it corrosive. In addition, even if external factors such as impact occur on the repaired section, it has a technical feature that can prevent re-damage through improvement of material properties.
