Abstract: 
Initially durability and service life of reinforced concrete structures have been considered under the influence of one single action as for instance chloride penetration, carbonation or frost action. It could be shown in the meantime, however, that the effect of simultaneously or consecutively acting deteriorating processes is more severe than the effect of any single action participating in the deteriorating process. A number of actions, which are known to act frequently in common, has been selected from the huge number of possible load combinations and their deteriorating effect has been studied. Results show that chloride penetration and carbonation after frost action are significantly accelerated. The influence of mechanical tensile and compressive load on rate of carbonation has also been studied. Results can serve as a basis for more realistic prediction of service life of concrete structures exposed to an aggressive environment.
