摘要
Provided are: a high early strength agent for cements, which exhibits excellent initial strength developability and excellent fluidity, while having excellent storage stability; a high early strength cement which uses this high early strength agent for cements; and a method for producing a high early strength cement concrete. This high early strength agent for cements contains 30-60% by mass of nitric acid or a salt thereof, 0.1-10% by mass of a carboxylic acid or a salt thereof, and water; and the elemental calcium concentration in the high early strength agent is 5-20% by mass.
