Heat of Hydration
Introduction
Soon after casting, mass concrete structures go through a hydration period generating significant internal heat and a
corresponding increase in temperatures. Any differential expansion that accompanies this temperature rise leads to
internal thermal stressing that, in turn, may cause undesirable cracking. It is therefore important to perform a transient
heat analysis to determine the evolution of temperatures in hydrating concrete. As concrete structures are cast in stages,
a construction sequence must be incorporated into the heat of hydration analysis.
Problem
This example models a foundation structure consisting of subsoil mass and two parts of mass
concrete cast in two stages.
The 2nd pour takes place after 170 hours of casting the 1st pour.
A quarter model heat of hydration analysis is required for the duration of time up to 930 hours
after the casting of the 2nd concrete mass in order to determine:
• The temperature history within the 1st concrete mass
• The temperature history at the interface between the two concrete parts
