If a stain is set in or is particularly hard to remove, try a commercial product like hydrochloric acid (but avoid using it on concrete floors) or call a cleaning professional you trust.
Hydrochloric acid is a common mineral acid typically used for concrete. Vinegar can also be used to clean hard surfaces and remove calcium deposits. Sulphuric acid is used in acidic drain cleaners to unblock clogged pipes by dissolving organic materials, like greases, proteins, and even carbohydrate -containing substances such as toilet tissue.
glycolic acid; sulfamic acid; disodium capryloamphodipropionate; ethylene glycol n-butyl ether; citric acid; One formulation is (by weight) lactic acid 12–18%, gluconic acid 2.50–3.75%, lauramine oxide 1.50–3.25%, with the remainder being water. [3] The product also contained phosphoric acid at one time, [citation needed] but it is now ...
Acidic drain cleaners usually contain sulfuric acid at high concentrations. [1] It can dissolve cellulose, proteins like hair, and fats via acid hydrolysis. While there are many methods for unclogging drains, one of the most effective solutions is using hydrochloric acid (HCl), a powerful chemical cleaner. [2]
Michigan Concrete Association recommends a regular salt like Morton table salt instead of an ice melter because it’s 100 percent sodium chloride (NaCl). This, however, is recommended for ...
Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.
Calcium aluminates can form complex salts in combination with different types of anions.Two series of calcium aluminates are known in cement chemistry: AFm and AFt phases, being respectively mono- or tri-substituted with a given divalent anion X (e.g. SO 2− 4, CO 2− 3, or hosting a divalent impurity such as SeO 2− 4 [3]...), or with two units of a monovalent anion, e.g. OH −, Cl − ...
The necessary additional calcium is provided by the calcium hydroxide and calcium silicate hydrate in the cement paste; The effect of these changes is an overall loss of concrete strength. The above effects are typical of attack by solutions of sodium sulfate or potassium sulfate. Solutions containing magnesium sulfate are generally more ...
