000003444 520__ $$2eng$$aThe mechanical behaviour of solidifying and further hardening concrete is influenced by the rapidly progressing hydration which makes the experimental work difficult and as a result there is few experimental data for concrete at such early ages. Since the Chen model of plasticity is very suitable for modelling of hardened concrete due to the different strengths considered in compression and tension, it was sought to make use of this model also for description of mechanical behaviour of hardening concrete. The material parameters considered in the modelling have to be dependent on the progressing hydration. The hydration is quantified with help of the degree of hydration. The performance of the modified Chen model of plasticity is described in an illustrative example.
