Pool anti-corrosion

To prevent leaks, two concrete tanks are needed; what materials would be suitable for anti-corrosion treatment of these tanks?
The ground should be covered with stones; it’s all concentrated acid with strong oxidizing properties. It’s advisable to have fire-fighting water facilities, eye wash stations, and emergency water supplies in the vicinity； The inside of the tank should be coated with an anti-oxidation, corrosion-resistant paint; it’s best to use thick stone bricks for the floor. I’ve seen cofferdams made of concentrated sulfuric acid that have been in use for 3–5 years, and the stone bricks showed little signs of corrosion, though the gaps and areas where the bricks had fallen off were not attractive. Safety comes first.
:), is it an open pool? ?
The highest concentration of hydrochloric acid is 36.5%; a 30% hydrochloric acid concentration is very high； 98% concentrated sulfuric acid is fuming sulfuric acid, which has strong oxidizing properties. For these two types of media, 1032 high-oxidation-resistant anti-corrosion coating should be used for protection; the cofferdams and other associated structures also require this coating for protection. The cement pool can be constructed after undergoing a normal cement curing period of over 28 days. After the cement’s moisture content is tested and found to be satisfactory, a special sealing primer is applied; the quality of this sealing process has a direct impact on the success of subsequent anti-corrosion measures. After applying the sealant, the anti-corrosion coating can be applied directly without the need for a backing fabric; multiple application coats are sufficient to achieve a dry film thickness of >300μm. The coating can be put into use after being cured at room temperature for more than 72 hours to ensure it is dry.
