REPAIRING MATERIAL OF DETERIORATED CONCRETE AND REPAIRING METHOD

摘要

PURPOSE:To suppress expansion and deterioration of concrete by pouring a repairing material containing an alkali-resistant ion absorbing material capable of absorbing an alkali metal ion in a concrete compound into a crack of the concrete. CONSTITUTION:An alkali-resistant ion absorbing material capable of absorbing an alkali metal ion such as Na ion, K ion, etc., contained in a concrete compound is prepared. The alkali-resistant ion absorbing material is kneaded with an inorganic binder and water to form the repairing material. The resultant repairing material is poured into a crack, etc., of a concrete or applied to the surface of the concrete to cure the repairing material.
