ACI 207.4R

Description / Abstract: The need to control volume change induced primarily by temperature change in mass concrete often requires cooling and insulating systems. This report discusses three construction procedures used to control temperature changes in concrete structures: precooling of materials, postcooling of in-place concrete by embedded pipes, and surface insulation. Other design and construction practices, such as selection of cementing materials, aggregates, chemical admixtures, cement content, or strength requirements, are not within the scope of this report. The objective of this report is to offer guidance on the selection and application of these procedures for reducing thermal cracking in all types of concrete structures.
