I found this... Cement Tank Linings work very well in pressure vessels such as DHW-DCW tanks. PH is really your only concern with other applications.
NSF-61 certification is required for potable water applications, however there are not too many cement based coatings on the market that conform with NSF-61. Raw materials found in many cement mixes are often contaminated and not suitable for human consumption.
NOTE: Portland cement, mixed with sand is not considered NSF-61 certified since you cannot mix a non-certified ingredient or additive to an NSF-61 certified product without voiding the original certification.
You will need to find the correct cement lining product for your storage tank on either the CSA or NSF websites.
Hope this helps,
