Rapid-hardening mortar composition
This rapid-hardening mortar composition includes a rapid-hardening admixture, cement, and a fine aggregate. The composition contains 100-2000 parts by mass of the cement per 100 parts by mass of the rapid-hardening admixture. The rapid-hardening admixture includes calcium aluminate, 50-200 parts by mass of an inorganic sulfate per 100 parts by mass of the calcium aluminate, and 0.1-10 parts by mass of a setting regulator per 100 parts by mass of the calcium aluminate. The average particle diameter of the calcium aluminate is 8-100 μm. The average particle diameter of the setting regulator is 5 μm or less.
