NON-SHRINKAGE GROUT COMPOSITION, AND NON-SHRINKAGE GROUT MATERIAL

摘要

To provide a non-shrinkage grout composition and a non-shrinkage grout material that have non-shrinkable and high strength property, high fluidity, and exhibit crack self-healing property against crack generated in a structure by the self-healing property.SOLUTION: A non-shrinkage grout composition is configured with a cement binder, mixture binder blended by 5 to 20 mass% of fraction based on the cement binder of 100 mass%, fine aggregates blended by 15 to 55 mass% of fraction, an expansion swelling admixture blended by 1 to 15 mass% of fraction, a water-soluble inorganic-based gelatinizer blended by 1 to 15 mass% of fraction, a high performance water-reducing agent blended by 0.01 to 2.00 mass% of fraction, and fiber reinforcement materials blended by 0.01 to 2.00 mass% of fraction.SELECTED DRAWING: Figure 1
