[en] A diffusion theory with a linear or a nonlinear coefficient of diffusivity is insufficient for the characterization of the drying behaviour of hydrated concrete slabs. A general mathematical model, based on nonequilibrium, irreversible flows of heat and mass, yields a set of nonlinear partial differential equations of parabolic type. Implicit finite difference calculations for a concrete slab yield moisture, temperature, and pressure histories as well as global average drying rates. Graphs show that during the pendular state of dessication, diffusion, capillary, and evaporation-condensation processes are the governing mechanisms in drying. (orig.)

[en] The possibility of using numerical method for the analysis of reinforced concrete structures is limited by the incomplete knowledge of the behavior of concrete under multiaxial stress states. While many experimental and theorectical investigations have been and are presently carried out to clarify this problem, an attempt is being made here to use the available experimental data to achieve an ultimate strength criterion apt to be used in an analytical model.
