Research Status and Prospect of Constitutive Relation for Concrete after Freeze-Thaw Damage

Frost resistance is one of the most important indexes of concrete durability, therefore it is essential for the research of constitutive relation for concrete after freeze-thaw damage. The constitutive relation for concrete is directly related to the rationality and security of the structural design. The existing research mainly includes experimental and theoretical simulation, and has made several progresses. Based on the summary of the existing constitutive relation for concrete after freeze-thaw damage, this article puts forward its own idea on the development tendency. And it provides reference for the further study of the constitutive relation for concrete after freeze-thaw damage.
