Rapid-hardening admixture and method for producing same
The present invention provides a rapid-hardening admixture for accelerating hardening of a cement composition and a method for producing the same. The rapid-hardening admixture includes calcium aluminate, inorganic sulfate, and a setting modifier, in which the calcium aluminate has an average particle diameter in a range of 8 μm to 100 μm, and the setting modifier has an average particle diameter of 5 μm or less.
