ABSTRACT
Quality control, protection of objects made of reinforced concrete is a many-sided problem. It is solved by perfection of the quality control methods, introduction of the quality securing system. Reinforced concrete constructions should be protected against corrosion and their crack resistance must be secured with the purpose of building equally reliable and equally durable constructions in the system of the object. If the above mentioned conditions are not secured, at the designing stage the reconditioning must be envisaged with minimum economic and material losses for the object operation.
