The formation of a powdery surface on crystals, as a hydrate is converted to anhydrous form by losing loosely bound water of crystallization to the atmosphere
An encrustation of soluble salts, commonly white, deposited on the surface of stone, brick, plaster, or mortar; usually caused by free alkalies leached from mortar or adjacent concrete as moisture moves through it
A deposit or encrustation of soluble salts, generally white and most commonly consisting of calcium sulfate, that may form on the surface of stone, brick, concrete, or mortar when moisture moves through and evaporates on the masonry Often caused by free alkalies leached from mortar, grout, adjacent concrete, or in clays
(1) (Chemistry) The deposit that results from the process of Efflorescing, called bloom (2) A growth of salt crystals on a surface caused by evaporation of salt-laden water ADVANCE \x 540
(Blooming) Alkali migration to the surface of sodium silicate films Carbon dioxide in air reacts with the alkali forming sodium carbonate Less likely to occur with potassium silicate films [Top]
the formulation of crystalline deposits, generally whitish in color, on the surface of stone, brick, concrete, or other masonry surface when moisture moves through and evaporates on the masonry May also be caused by free alkalies leached from mortar, grout, or adjacent concrete
A white powdery substance that can form on new block, brick, or stucco finishes It is composed of water soluble salts that are present in masonry materials and that rise to the surface via water evaporation
An encrustation of soluble salts, commonly white, deposited on the surface of coatings, stone, brick, plaster, or mortar; usually caused by salts or free alkalies leached from mortar or adjacent concrete as moisture moves through it
The accumulation of minerals on an exposed surface often due to moisture migrating through a masonry wall, evaporating, and leaving the dissolved minerals in the moisture on the exposed surface
