The present invention relates to a repair reinforcement in concrete structures with a composition mortar for repairing concrete structures reinforcement and this, more specifically, a long time maintain the effect of improving the durability and the bonding strength here as repairing the damaged portion of the deteriorated concrete structures At the same time it is possible to reliably complete the repair work in a short period of time economy is also excellent, and excellent in neutralizing the effect of preventing the concrete and, in particular, and can enhance the water-tightness to minimize the influence of the external atmospheric environment such as acid rain, a binder, and agents which the optimum ratio mix by condensation rate control and in hard to exert be in the concrete structure of the rehabilitation process to provide it.
When repairing a damaged portion of the concrete structure by using the method according to the invention, the bending strength, tensile strength and compressive strength and physical properties very excellent, excellent in adhesion performance of the concrete structure, and the chemical resistance, and water resistance is also excellent, excellent resistance to freezing and thawing and chloride attack, and may improve the cure rate of the mortar is neutralized preventing effect and waterproofing effect can be increased. In particular, it is possible to enhance the water-tightness to minimize the influence of the external atmospheric environment such as acid rain, the binder and the benefit of controlling the solidification velocity and exhibit in rigid by mixing the agent to the optimal ratio. In addition, a long period of time to maintain the repair reinforcement effect by the adhesive force of the for the lower recovery mortar excellent in use in impact resistance, chemical resistance, water resistance, carbonation-resistant, corrosion resistance, antibacterial properties, antifouling properties, air permeability, excellent surface protective agent properties such as weather resistance there is an effect that it is possible.
