RAPID-HARDENING ADMIXTURE AND SPRAYED CONCRETE
To provide a rapid-hardening admixture that expresses strength for a long time even under a high temperature environment, and sprayed concrete.SOLUTION: A rapid-hardening admixture contains calcium aluminate, aluminum sulfate, alkali metal sulfate and alkaline earth metal sulfate. The alkali metal sulfate contains free water the amount of which is 0.08-0.85 mass% relative to the total mass of the alkali metal sulfate.SELECTED DRAWING: None
