Description

technical field

[0001] The present invention relates to an early strengthening agent for a hydraulic composition, an additive composition for a hydraulic composition, a hydraulic composition, a method for producing the hydraulic composition, and a method for producing a hardened body of the hydraulic composition. Background technique

[0002] Concrete products are made by mixing materials such as cement, aggregate, water and dispersants and pouring them into various types of boxes, and then undergoing a curing (hardening) process to make products. From the point of view of improving productivity, that is, increasing the turnover rate of the mold box, it is important to exhibit high strength at the initial material age. For this reason, the following countermeasures are proposed: (1) Use early-strength cement as cement; (2) Use various polymers Carboxylic acid compounds are used as admixtures to reduce the amount of water in cement compositions; (3) Steam curing is used as a ...
