	Rosendale Natural Cement was a common material of construction for large masonry and early concrete structures in the 19th and early 20th Centuries in eastern USA. It was prized for its fast early set, allowing much more rapid construction than lime putty masonry mortars. It was also recognized for its exceptional durability, even under severe exposures. Rosendale cements contained 10-30% MgO depending on the manufacturer and quarry.	17 April 2006
