Concrete Chemistry and Protective Coatings

Concrete is composed of cement, water and aggregate. Aggregate is the sand and gravel used in concrete – composing 60 to 75% of the concrete. Like the extender pigments used in paints, the aggregate is a relatively low-cost ingredient (relative to the cement) and it keeps the cost of the concrete low.

Building Mexico: The Many Faces of Mexican Concrete

Mexico's largest cement producer, Cemex (see elsewhere in this issue) was founded in 1906, and its second largest, Cementos Apasco, was organized in 1928. Ultimately Cemex cornered the export market, while Apasco (bought by the Swiss conglomerate Holcim in 1964) dominates the internal market for cement products.
