<P>PROBLEM TO BE SOLVED: To provide a cement composition which does not reduce an effect of a dispersant added in order to secure flowability, while suppressing hydration heat generated by a reaction of cement with water, when producing concrete, mortar or the like having a low water/cement ratio. <P>SOLUTION: This cement composition used at a water/cement ratio of ≤40% contains a hydration heat inhibitor containing tannin extracted from legume Caesalpinia spinosa or tannin extracted from Terminalia chebula, and a dispersant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
