Secondary efflorescence on the dam of the Robert Moses Niagara Power Plant. In chemistry, efflorescence (which roughly means "the flowering" in French) is the migration of a salt to the surface of a porous material, where it forms a coating. The essential process involves the dissolving of an internally held salt in water or occasionally, in ...
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
The concrete industry uses calcium stearate for efflorescence control of cementitious products used in the production of concrete masonry units i.e. paver and block, as well as waterproofing. [3] In paper production, calcium stearate is used as a lubricant to provide good gloss, preventing dusting and fold cracking in paper and paperboard ...
Saltpeter Mine Ruins in Mammoth Cave. The process involved burial of excrements (human or animal) in the fields prepared for that purpose beside the nitraries, watering them and waiting until the leaching process did its job; after a certain time, operators gathered the saltpeter that "came out" to the ground surface by efflorescence.

I tried six brands of store-bought tater tots from Sonic, Ore-Ida, Cascadian Farm, McCain, Signature Select, and Alexia Foods to find the best ones.
Cement hydration and strength development mainly depend on two silicate phases: tricalcium silicate (C 3 S) (), and dicalcium silicate (C 2 S) (). [1] Upon hydration, the main reaction products are calcium silicate hydrates (C-S-H) and calcium hydroxide Ca(OH) 2, written as CH in the cement chemist notation.
