Abstract

An extension of the Chen model of plasticity for the use with concrete in the very early ages is described in this paper. Since the Chen model of plasticity is very suit-able for modeling of hardened concrete due to different strengths considered in compression and tension, it was sought to make use of this model also for the description of mechanical behavior of hardening concrete. The material parameters considered in the modeling have to be depend-ent on the progressing hydration. The hydration is quanti-fied with help of the degree of hydration. Due to this modi-fication the application range of the Chen model can be extended to hardening concrete.
