The deterioration of reinforced concrete water - supply towers in Lithuania

The period of 1950 – 1980 was most intensive for water – supply towers construction in Lithuania. The purpose of water – supply towers – to increase the water pressure and to supply with water consumers residing far away from central stations. Under the influence of loads and negative environmental impacts water – supply towers constructions are wear out, and deteriorations are formed. The technical state of water – supply towers should be evaluated before planning repairs or reconstruction. Special research or studies of technical state evaluation of reinforced concrete water – supply towers were not performed in Lithuania. The aim – to establish the main deteriorations and to evaluate the technical state of reinforced concrete water – supply towers. The most commonly occurring water – supply towers deteriorations are cracks in the concrete surface by 0.2 to 0.3 mm wide, surface delamination. One of the most dangerous deteriorations is corrosion of reinforcement and concreteVytauto Didžiojo universitetasŽemės ūkio akademij
