In an industrial plant with continuous production, there were two breakdowns in the company’s sewage treatment plant for liquids with a high sulfuric acid content. Despite securing the underground walls of reinforced concrete tanks with protective coatings resistant to the impact of highly concentrated solutions with sulfuric acid as well as liquids with high alkaline concentration, there was sulphate corrosion destroying the insulation and structural reinforcement. The reasons for the failure were simultaneously improperly selected protective coatings and the technology of applying these coatings to the walls of tanks. In addition, the appearance of cracks in concrete and in polypropylene slabs is influenced by the rheology of construction materials, which is permanently ignored in the construction of multi-layer walls.
