What treatment is recommended for the interior of concrete tanks which are to be used for the storage of molasses?
If the concrete itself is of good quality and thoroughly cured and dried, the chances are that no protection will be needed. Wet curing for at least a week, and air drying for not less than 3 weeks, should be regarded as essential to produce concrete capable of standing up under this type of exposure. An additional margin of protection would undoubtedly be afforded by treatment with such materials as magnesium or zinc fluosilicate, or sodium silicate (water glass).
