Rosendale cement refers to a type of natural cement produced in and around Rosendale, New York. Because of its reputation, "Rosendale Cement" has also been used as a generic term to refer to natural hydraulic cement produced elsewhere. It was used in the construction of many of the United States most important landmarks, including the Brooklyn Bridge, the pedestal of the Statue of Liberty, Federal Hall, and one of the wings of the United States Capitol building.
Natural cement is produced in a simple process that begins with the calcination of crushed carbonate sedimentary rocks in kilns. The resulting clinker is ground into a fine powder before being shipped to market. Historically, this natural cement product was packaged in paper-lined wooden barrels or heavy canvas bags.
