When concrete is used for equalizing tank or Neutralizing tank in dye waste treatment plant, continuous exposure of different chemicals during treatment of waste water, it can attack the concrete in different ways beacuse each dye factory have different chemicals for Coloring different materials.can any one suggest the preventive measures to protect concrete particularly in dye waste treatment plant.
Bala Murali:
Concrete corrosion is mainly caused by :
- Salt water or acidic ground water
- Microbes in sewer pipes
- Sulphates
- Chlorides
- Nitrates
- Fluorides
- Sulphides
- Industrial waste like slag and corrosive gases
- Biological sulfuric acid attack is a chronic problem in sewage pipes, leading to rapid deterioration of concrete. Because of the role of bacteria in the corrosion reaction, mechanical engineers have focused on the study of corrosion resistance of different concrete mixes in an effort to prevent this type of corrosion. (https://www.corrosionpedia.com/definition/1320/concrete-corrosion).
So you have to detect which corrosives are present in your wastewater to be able to take some protective measures.

The water causes the hardening of concrete through a process called hydration. Hydration is a chemical reaction in which the major compounds in cement form chemical bonds with water molecules and become hydrates or hydration products.
