The knowledge of material properties of solidifying concrete is of major importance during construction process when many subsequent damages can be prevented. In this paper an evolutionary material model which can be used during the whole period when solidifying concrete undergoes the transition from a liquid to a solid state is proposed. The evolution of the material parameters is governed by a function of water/cement ratio and elapsed time after mixing which corresponds to the degree of hydration of concrete. The model can be used for modeling uniaxial behavoir of solidifying concrete including creep. The parameters for the evolutionary function were determined from three experimental methods for uniaxial loading.
