ABSTRACT
At the beginning of the 20th century, when reinforced concrete entered definitely our living environment as a structural material, it was considered to be a material which will last forever and not require any maintenance during a structures’ exploitation. Nowadays, designed reinforced concrete structures should have a service life of about one hundred years under normal environmental conditions (e.g. Gulvanessian et al. 2012). This process takes into account life-cycle design and management of concrete structures relative to long-life exploitation, environmental influences, deterioration over time (Budelmann et al. 2012, Kumar et al. 2013), and also prediction of service repair work (Wachsmann & Budelmann 2012). Even though concrete structures can suffer deterioration after a very short period of time (e.g. Berkowski et al. 2013), they can also stay in a quite good structural and material condition after many years of use, which will be presented in this paper.
