One of important problems of road reinforced concrete bridges is corrosion of steel reinforced members caused by chlorides ingress. In landlocked countries the main source of chlorides is their use as anti-freezing agents on roads. There is a set of measures which can be used to minimize the problem of chlorides ingress in structural concrete. Proper design of concrete mixtures can enhance material resistance to chlorides ingress. This design should be based on known parameters of experimentally tested mixtures. Parameters of the designed mixtures can be approximated from these data. Then the numerical analysis of structures designed with the use of such mixture has to be carried out. An initial analysis can be done by the use of a simple model but more precise results can be obtained by finite element modeling. The problem requires the use of approaches of structural reliability, thus often theMonte Carlo-type computations are required. These approaches usually require relatively large amount of computation and parallel processing of these computations is one of the best ways to make them more feasible. The contribution discusses used approaches in detail. The numerical simulations will be discussed for 2D models. Comparison of results will be shown and times required to analyse the most important parts of problem will be presented
