Most densifiers can react within 1-2 hours with concrete surface, however the chemical reaction with the calcium and free lime in the concrete will continue for up to 2 months after the application of it to the surface of the concrete. Densifiers may use various carrying agents to accomplish the hardening process, potassium, sodium, lithium, or ...
Sodium hypochlorite is an alkaline inorganic chemical compound with the formula Na O Cl (also written as NaClO). It is commonly known in a dilute aqueous solution as bleach or chlorine bleach. [4] It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −
Concrete sealers are applied to concrete to protect it from surface damage, corrosion, and staining. They either block the pores in the concrete to reduce absorption of water and salts or form an impermeable layer which prevents such materials from passing.
Soft washing is a cleaning method using low pressure water. More recently, the term "softwashing" has been used to describe any form of spraying chemicals at buildings where solutions (typically sodium hypochlorite based softwashing chemicals) are used to remove mildew, bacteria, algae and other organic stains from roofs and other building exteriors.
It is used as an alternative to chlorine and sodium hypochlorite for disinfection of drinking water and swimming pools. Chloramine-T, or tosylchloramide sodium salt, [(H 3 C)(C 6 H 4)(SO 2)(NHCl)] − Na +. This solid compound is available in tablet or powder form, and used in medical establishments to disinfect surfaces, equipment, and ...
In chemistry, hypochlorite, or chloroxide is an anion with the chemical formula ClO −. It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). [1] The Cl-O distance in ClO − is 1.69 Å ...
Dakin's original solution contained sodium hypochlorite (0.4% to 0.5%), prepared by treating calcium hypochlorite with sodium carbonate ("washing soda"). The solution left after removal of the insoluble calcium carbonate still contained some soda. [7] Boric acid (4%) was then added as a buffering agent to maintain a pH of between 9 and 10.
Sulfates dissolved by ground moisture migrate into the concrete of the slab where they react with different mineral phases of the hardened cement paste. The attack arises from soils containing SO 2− 4 ions, such as MgSO 4 or Na 2 SO 4 soluble and hygroscopic salts.
