METHOD OF PREVENTING DETERIORATION OF CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method for preventing the deterioration of a concrete structure caused by the neutralization at a low cost. SOLUTION: An alkalinity recovering agent 7 is infiltrated into the inside of concrete 1 through cracks 5 by partially or wholly coating the surface of the concrete 1 of the concrete structure with the alkalinity recovering agent 7. After the alkalinity recovering agent 7 has been sufficiently infiltrated into the inside of the concrete 1 through the cracks 5, the surface of the concrete 1 is coated with a concrete protecting material 9 so as to form an acidic gas adsorbing surface layer 11. It is possible to coat the whole surface of the concrete 1 with the concrete protecting material 9.
