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 ...
Clean off with a wire brush all surfaces and any steel and pipe work within the area up to a radius of 1.5 metres from the furthest extent of suspected infection. Remove from the building all dust and debris ensuing from the work. Apply fungicide to all such masonry, concrete and earth surfaces at the specified rate. Apply two generous coats of ...
Crystallized salt clusters (efflorescence) produced by Byne's disease on a gastropod shell's surface Some affected mollusk shells. The efflorescence is clearly visible in both specimens. This decay was deliberately produced under extreme conditions. Byne's disease can appear as a powdery white coating on a shell or other calcareous specimen.
Step 1: Create a Rust-Removing Solution. Pour enough white vinegar into the container to fully submerge the rusty object. Add a generous amount of salt to the vinegar and stir until it dissolves ...
Example of secondary efflorescence in parking garage exposed to diluted road salt from vehicles entering the garage during winter. When water flows through cracks present in concrete, water may dissolve various minerals present in the hardened cement paste or in the aggregates, if the solution is unsaturated with respect to them.
Efflorescence is usually the result of mineral solutions in the capillary channels being drawn to the surface. If the water evaporates, the minerals remain as the so-called efflorescence. It also can be the result of chemical reaction; if badly prepared cement-based mortar is applied to maintain the stone in position, free calcium hydroxide may ...
