History of Rosendale Natural Cement

Natural Cement was used in the original construction of some of the most enduring landmarks of the nation: The Brooklyn Bridge, the pedestal of the Statue of Liberty, the wings of the U.S. Capitol, the lower 152’ of the Washington Monument, the Croton Aqueduct and dams, the Pennsylvania Railroad tunnels, the New York State Thruway, and thousands of other public works projects.

Since re-introduction in 2004, Rosendale Natural Cement Products® have been used successfully in dozens of restoration and special construction projects.

1798 Parker’s Roman Cement is patented in England, the first natural cement.

1818 Natural cement rock is discovered by Canvass White in Fayetteville, NY during the construction of the Erie Canal, beginning a 153-year run of continuous production of natural cement in New York State.

1824 Natural Cement production begins in Williamsville, NY

1825 Natural Cement limestone is discovered in Rosendale, New York.

1829 Natural Cement production begins in Louisville, KY

1836 Natural Cement production begins in Cumberland, MD

1837 Natural Cement production begins in Hancock, MD

1838 Natural Cement production begins in Utica, IL

1839 Natural Cement production begins in Akron, NY. Though distant from Rosendale, NY, the cement produced here is described as a Rosendale cement.

1848 Natural Cement production begins in Balcony Falls, VA

1850 Natural Cement production begins in Lehigh Valley, PA and Cement, GA. The cement produced in the Lehigh Valley, though distant from Rosendale, NY and somewhat different in its chemical composition, is often packaged and sold as Rosendale Cement. Later, products labeled as  “Improved Rosendale Cement” are marketed in this region, consisting of a blend of natural and portland cements.

1867 Natural Cement production begins in Fort Scott, KS

1869 Natural Cement production begins in LaSalle, IL

1870 Natural Cement production begins in Howes Cave, NY. Cement produced here, some 75 miles from Rosendale, NY, is marketed under the name “Rosendale Hydraulic Cement”.

1874 Natural Cement production begins in Buffalo, NY. Though distant from Rosendale, NY, the cement produced here is described as a Rosendale cement.

1875 Natural Cement production begins in Milwaukee, WI. The cement produced here is described as a Rosendale cement.

1883 Natural Cement production begins in Mankato, MN. The cement produced here is described as a Rosendale cement.

1883 The Brooklyn Bridge opens on May 24, its concrete-filled caissons and granite superstructure held together by Rosendale Natural Cement.

1886 President Grover Cleveland accepts the Statue of Liberty, a gift from the people of France, on behalf of the United States on October 28. The 154-foot, 27,000-ton pedestal is made with Rosendale Natural Cement.

1896 Natural Cement is in production at 71 sites in 17 US states. At least 2 or 3 sites are also active in Canada.

1904 ASTM Committee C adopts the first ASTM Standards for Natural and Portland Cements.

1954 The New York State Thruway opens, partially paved with Rosendale Natural Cement

1970 The last of the original Rosendale, NY cement mines is closed.

1976 The Fort Scott Hydraulic Cement Co. in Kansas shuts down, the last producer of natural cement as a finished product. Some manufacturers of masonry cements continue to use natural cement in their production, however.

1978 ASTM C10 Standard Specification for Natural Cement is withdrawn due to disuse.

2004 Edison Coatings, Inc. starts production of authentic Rosendale Natural Cement Products® for use in restoration of historic structures and monuments.

2006 ASTM C10 Standard Specification for Natural Cement is reinstated.


Natural cement was first used in the United States in the late 18th Century. In 1825, commercial mining and processing operations were begun in an area in New York’s Hudson Valley, in and around the town of Rosendale in Ulster County, and the area quickly developed into the largest single production source of natural cements. By 1830, nearly 10 million pounds per year of natural cement were being produced, marking the beginning of its commercialization. Ultimately, more than 71 sites in 17 states were producing a total of nearly 300 million pounds per year of natural cement in the late 19th Century. Collectively they became known as “Rosendale Cement”, the term becoming synonomous with “Natural Cement”.

As the Industrial Revolution began, the need arose to more quickly construct large masonry buildings. Fast-setting Natural Cement mortars proved more efficient than traditional mortars based on lime and sand. The advantages in construction of military fortifications were also soon realized, beginning the long-term use of Natural Cement by the U. S. Army Corps of Engineers. By 1850 annual consumption of natural cement grew to more than 300 million pounds.

Over the course of the 19th Century, the United States grew from a rural, agrarian economy to an urbanized industrial power. Early concrete, like the supports for the Brooklyn Bridge, began changing the face of American cities. Canals like the Delaware and Hudson helped to speed delivery of materials to their markets. Later, expansion of rail systems further accelerated transportation of passengers and goods. Construction of the Pennsylvania Railroad tunnels and Grand Central Station were part of that growth. In New York City, construction of the first light rail rapid transit system was beginning. All of these projects utilized Natural Cements.

As the 20th Century began, demand was for still higher strength, and still faster curing cements. Natural cement usage was quickly overtaken and surpassed by portland cement. Although Natural Cements remained in use for special applications as late as the 1960’s, the last of the original Rosendale, NY mining operations closed in 1970. Fort Scott Hydraulic Cement Co., in Fort Scott, KS, closed in 1976, the last manufacturer of Natural Cement as a finished product. For almost 30 years the material was no longer available.

Edison Coatings, Inc. restarted commercial production of Natural Cement in 2004. Edison’s Rosendale Natural Cement Products® are historically correct materials made from authentic, 100% natural cement rock extracted from the same deposits used for Natural Cement production in the 19th Century. Edison’s Rosendale Natural Cement Products® mortars, stuccos, grouts and concretes fully utilize the extensive engineering expertise developed in the use of natural cement in the 19th and 20th centuries.

Beyond the historical authenticity of Edison’s Rosendale Natural Cement Products®, however, the material offers a unique balance of performance properties that can only be fully appreciated through the hindsight of nearly 2 centuries of durable service. Whether a project involves restoration of a building or structure originally constructed with natural cement, or simply would benefit from a highly compatible, durable, user-friendly cement technology, discover Rosendale Natural Cement Products®.
