Concrete surfaces sometimes develop a white, streaky residue called efflorescence. As moisture in the slab evaporates, it carries natural salts to the surface, which create the powdery residue. A light power-washing can effectively remove the deposits.
Did you know that colored cement does not fade over time? In fact, the active ingredients in colored cement are made of inorganic pigments that have been oxidized so that they do not fade. In contrast, traditional uncolored cement can fade or yellow.
The Washington Post reported in 2015 that China’s rapid urbanization resulted in the country using up more cement in three years than what the US used throughout the entire 20th century.
Water leakage in newly finished concrete can rise to the surface, carrying with it fine aggregate debris, which makes it soft and potentially weakens the surface. Densifiers work to bind to available minerals (such as lime), creating a strong and long lasting surface.
Cement history: Modern Portland cement dates back nearly 200 years. This cement was invented in England in the year 1824.
Did you know that masonry construction provides better protection from burglaries? The same can be said about fire and severe weather conditions too. Stone’s permanence can withstand the huffs and puffs of the wildest things.
