how to reduce heat of hydration in concrete?

Answer / xevier
Since hydration of cement is exothermic, evolved heat is harmful to mass concrete and may cause thermal-shrinkage-induced cracking due to heat build-up in the concrete, frequently occurred in hot climate country. Heat generation can be reduced by replacing cement portion with pulverized-fuel ash, like PFAC, modification of clinker constituents, and fineness of cement. A reduction in temperature will retard the rate of hydration and so further restrict the rate of heat generation and reduce thermal shrinkage.
