Abstract

Concrete is a construction material that is extremely widely used in the construction of water management facilities. However, in the presence of hydrogen sulfide in the gas-air operating environment, concrete can undergo extremely aggressive biogenic sulfuric acid corrosion. The paper presents the results of an experimental chemical, physico-chemical and phase study of concrete samples from the surface part of the gravity sewage collector and the primary sump of the city sewage facilities and oil trap at the oil production site. It was proved that all concrete samples were subjected to biogenic sulfuric acid aggression, to the greatest extent – a sample from a city sewage collector.
