Concrete cleaning with a surface cleaner. There are 2 main types of pressure washers. Hot water pressure washers and cold water pressure washers. Each have their own purpose. [4] Hot water pressure washers are best for washing flatwork (concrete driveways, walkways, etc) that can have grease or oil residue. They are best to use when cleaning ...
The pH of a 1% solution is 12 (i.e., very basic), and the solution is sufficiently alkaline to saponify grease and oils. In combination with surfactants , TSP is an excellent agent for cleaning everything from laundry to concrete driveways.
This reaction is accompanied by hydration and swelling of the alkali gel leading to the expansion of the affected aggregates. The pH of the fresh alkali gel is very high and it has often a characteristic amber color. The high pH of young alkali gel exudations often precludes the growth of mosses at the surface of concrete crack infilling. 2.
The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]
McIlvaine buffer is a buffer solution composed of citric acid and disodium hydrogen phosphate, also known as citrate-phosphate buffer.It was introduced in 1921 by the United States agronomist Theodore Clinton McIlvaine (1875–1959) from West Virginia University, and it can be prepared in pH 2.2 to 8 by mixing two stock solutions.
Aqion is a hydrochemistry software tool. It bridges the gap between scientific software (such like PhreeqC [1]) and the calculation/handling of "simple" water-related tasks in daily routine practice.
Murphy Oil Soap is an American brand of cleaning product that is manufactured by Colgate-Palmolive. [1] In 1910, Jeremiah Murphy, director of the Phoenix Oil Company, bought the formula for Murphy Oil Soap from a recent immigrant from Germany. The soap, with its potassium vegetable oil base, and no phosphates, proved to be very popular in Ohio.
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.
