Abstract:
High-temperature gradients can occur in all concrete structures as the heat of hydration of the freshly placed concrete is liberated, and cracking can result at the surface. Problems due to the tensile stresses and cracks that are induced by the temperature gradients can be especially severe for thick concrete sections. The present investigation aims to reproduce conditions for early thermal movements in the laboratory site and to study their effects and possible control.
