Abstract:
Hydration of cement is an exothermic reaction causing a temperature rise in “young” or newly placed concrete. Temperature-induced stresses occur if temperature deformations are restrained, which can cause cracking of the concrete if stresses exceed the strength of the concrete. Calculating temperature-induced stresses in young concrete is complex and can only be handled by computers. Today, fast personal computers along with finite element models exist to handle the difficult nonlinear process of modeling for temperature-induced stress.We describe how a finite element model is used to find measures to control concrete temperatures and thermal stresses.
