HIGH-EARLY-STRENGTH AGENT FOR HYDRAULIC COMPOSITION
To provide a high-early-strength agent for a hydraulic composition and a manufacturing method for the same, the high-early-strength agent having excellent workability during transport and during hydraulic composition preparation due to its low viscosity during shearing, and improving the strength of a cured hydraulic composition product after 5 to 20 hours, for example, following preparation, and a hydraulic composition and a manufacturing method for the same, the hydraulic composition capable of improving the strength of the cured hydraulic composition product after 5 to 20 hours, for example, following preparation.SOLUTION: A high-early-strength agent for a hydraulic composition contains a component (a), a component (b), and water. Component (a): calcite. Component (b): a copolymer containing a monomer (1b) expressed by general formula (1b) and a monomer (2b) expressed by general formula (2b) as constituent monomers, where, in all constituent monomers, a ratio of the monomer (1b) in the total amount of the monomer (1b) and the monomer (2b) is 10 mass% or more and 35 mass% or less.SELECTED DRAWING: None
