Definition of hot cement American Concrete Institute

Definition Of Hot Cement American Concrete Institute

Hot concrete in hot weather is subject to high loss of moisture by evaporation and rapid hardening, which affect the placement operations and the cracking potential. Because the cement fresh from grinding mills is hotter than the other materials, it is frequently considered the sole cause of the trouble. This gave rise to the term hot cement.
