Abstract: Early age thermal cracking in hardening massive concrete elements is a complicated issue. A detailed study of this phenomenon needs to take into account the evolving nature of thermal and mechanical material properties. A fundamental approach is provided by the degree of hydration concept. Within this concept, material properties are related to the microstructural development during the hydration process. This also includes the time dependent creep and relaxation behaviour. The degree of hydration concept can be implemented in finite element codes, enabling the evaluation of crack risks, and the optimization of the casting process. An overview is given of the degree of hydration concept, and some illustrative example is given.
