摘要

PROBLEM TO BE SOLVED: To provide an inhibitor for heat of hydration of cement that is applicable to a normal concrete admixture, maintains fluidity even if the amount of water used for a cement material is decreased, sufficiently inhibits heat of hydration, and is capable of producing concrete of high strength.;SOLUTION: The inhibitor for heat of hydration of cement comprises a dispersant and a chelate agent. The chelate agent preferably is at least one species selected from the group consisting of citric acid, ethylene diamine tetraacetic acid, hydroxy ethane diphosphonic acid, nitrilotriacetic acid, and hydroxyethyl ethylenediamine triacetic acid. The dispersant preferably is a hydroxy-carboxylic acid based dispersant.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
