application of what kind of special concrete for concrete structures in wastewater treatment plants is recommended for extend the life of concrete structures.Does the project which this type of concrete used to know and please introduce technical reference.
Dear Vahid Abdolvahab,
I suggest you to use UHPFRC as its permeability property is extremely low compared to normal concrete. You can refer to the attached article for further details.
Kind regards

For tanks that contain wastewater, the chemical resistance of the coating is extremely important. For the coating to be successful in protecting the concrete, it must be resistant to the particular chemicals at certain concentrations in the contained wastewater. The best way to determine if a particular coating is resistant to the wastewater in question is through laboratory analysis. This option often is not economically feasible for the job at hand. When this is the case, the owner or engineer should ask for reference projects from the coating manufacturer (preferably projects with similar exposure conditions).
For wastewater tanks, epoxy coatings offer a high degree of chemical resistance and ease of application. More specifically, the standard liquid bisphenol A epoxy with polyamine hardener has proven to be very durable in wastewater tanks. Other coating technologies such as polyureas, urethanes and vinyl esters also offer a high degree of chemical resistance but often are not easily applied.
kinds of concrete not important you can use many kinds of additives to protect concrete
and its important to know your wastewater have which kind of properties and characteristics and use especial materials for that kind of material.
its better to use case study and especial additives for your project.
