摘要：
PROBLEM TO BE SOLVED: To provide a crack self-repair concrete admixture which can self-repair a crack generated in a concrete structure without requiring artificial repairing or the like, and can increase the long term durability of the concrete structure, to provide a method for producing the same, and to provide a crack self-repair concrete material using the concrete admixture. SOLUTION: The crack self-repair concrete admixture is composed of granules comprising cement, water in an amount less than the theoretical water content required for the hydration of the cement, and magnesium hexafluorosilicate, and having the average particle diameter of 30 to 50 μm, wherein the concrete admixture is blended by 10 to 30 pts.mass based on 100 pts.mass of the cement.
