PROJECT PROFILE WJE www.wje.com CLIENT State Department of Transportation BACKGROUND A maximum temperature limit during concrete curing is specified to avoid the risk of delayed ettringite formation (DEF). DEF is usually occurs when its normal formation is postponed due to exposure to elevated temperature during initial curing, typically achieved either via heat-curing or through the heat of hydration of the cementitious materials, or both. Heat cured products and mass concrete elements are most susceptible to elevated temperatures during early hydration.
