WATER LEAKAGE CRACK WATER-STOPPING MATERIAL USING HIGH-PERFORMANCE INORGANIC CRACK INJECTION MATERIAL AND WATER-STOPPING METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To develop a water-stopping material suitable for repair of concrete structures and provide a water leakage crack water-stopping material which takes into consideration, a water-stopping effect and durability in carrying out construction work using the water-stopping material and uses a high-performance inorganic crack injection material and a water-stopping method using it.SOLUTION: A water leakage crack water-stopping material using a high-performance inorganic crack injection material uses a high-performance inorganic injection material consisting of a grout material prepared by kneading together three ingredients consisting of a high-performance reaction promotor based on sodium silicate for repair and water stopping of cracks having crack widths of 0.2 mm or greater, an admixture based on calcium nitrate and fine-particle blast furnace slag cement.
