摘要

PROBLEM TO BE SOLVED: To provide a crack repairing agent for a concrete structure and its repairing construction method which is inexpensive and short in construction period and can be carried out inexpensively, and can certainly repair a crack of the concrete structure to prevent a water leakage. ;SOLUTION: A crack repairing agent for a concrete structure is composed by adding alcohol by 1-60% into the water solution of 1-25% calcium compound. A solution formed by adding the alcohol into a water solution of a calcium compound is injected into the crack 2 of the concrete structure 1 to quickly dry the solution owing to the action of alcohol can to form a crystallizing body of calcium compound, and thus the crystallizing body fills up the crack.;COPYRIGHT: (C)1999,JPO
