Abstract

Concrete bridges life time affecting several factors. Corrosion of reinforcement caused by deicing salts penetration through the concrete bridges is one of the critical. Modeling of concrete degradation is the current task with a lot of random input parameters. There is needed large number of simulation steps in the probabilistic assessment using Monte Carlo. That leads to time-consuming calculations even in current level of computerization. Programming algorithm to accelerate the process of calculation is the aim of the research. The first step is the preparation and implementation of the algorithm in MatLab software. It is not fast, but it seems to be a useful tool for understanding the problem. The work discusses preparation of a model of transient diffusion of chloride, calculation of the chloride concentration and the example shows the functionality of the program.
