The Deterioration of Concrete in Wastewater Treatment Plants

Nowadays, concrete is the main material used in wastewater treatment plant construction. However, the presence of micro-organisms in wastewater results with in the deterioration of concrete and corrosion of the reinforcement steel bars. Therefore, durability of the concrete used for wastewater treatment plant should be very high in

Concrete Deterioration Caused by Sulfuric Acid Attack

Recently, biological deterioration of concrete in sewage and wastewater treatment plants has been reported. This deterioration is caused by sulfuric acid attack and is dependent on the concentration of sulfuric acid, this in turn being a function of both the specific location within the plant and also the time over which the concrete is exposed to elevated concentrations of acid. Given that ...
