Price of heat of hydration equipments for concrete cement

Apr 22, 2021

The mixing of cement with water will result in rapid evolution of heat that will last for few minutes. This evolution of heat is probably due to the reaction of a solution of aluminates and the sulfates. This rapid heat and reaction are depressed by the addition of gypsum. The Early heat of hydration is due to the hydration of C3S
