EFFECT OF ENVIRONMENTAL CONDITIONS ON SERVICE LIFE OF CONCRETE STRUCTURES
An assessment of the service life of new types of concrete using combined computational-experimental approach is presented in the paper. In the experimental part, durability of selected concretes is determined in terms of their frost resistance. A diffusion-type model is used for the description of coupled heat, moisture and salt transport aimed at the identification of the number of frost cycles in a real structure. In a practical application of the model, a concrete wall provided with exterior thermal insulation system and both exterior and interior renders is analyzed. Influence of salt presence on hygrothermal performance of used building materials is evaluated.
