The paper presents a study of the processes of reinforcement corrosion in concrete structures as a consequence of aggressive infiltration of water through cracks in the concrete. The rate of corrosion of reinforcement in concrete depends on the density and moisture content of concrete. Determine the influence of relative air humidity (60%, 80%, 95%) on the rate of corrosion of steel in the crack was made in chambers termohidrostatice at 50 0C, at high concentrations of oxygen and carbon dioxide than the environment. Duration of tests, depending on the degree of aggressiveness of the medium ranged from several days to several months. During the tests, controlled temperature, relative humidity, gas concentration, humidity of the concrete and the environment. When humidity variation from 35 to 60 %, the resistance of concrete increases slightly. The relative humidity increased to 80 % and more, the ohmic resistance decreases and the corrosion of reinforcement may have an intensive development. |
