Why monitor temperature in hot weather concreting?
Great question, glad you asked. If the internal temperature of fresh concrete exceeds 158-160°F, the hydration process of the cement is altered, increasing the potential risk of delayed ettringite formation and excessive or drying shrinkage.
DEF often does not appear for years after the concrete is poured, but once it does, it causes severe cracking that cannot be stopped.
