43:, beginning in 1825. From 1818 to 1970 natural cements were produced in over 70 locations in the United States and Canada. More than half of the 35 million tons of natural cement produced in the United States originated with cement rock mined in Ulster County, New York, in and around the Town of Rosendale in the Hudson River Valley. The Rosendale region of southeastern New York State is widely recognized as the source of the highest quality natural cement in North America. The Rosendale region was also coveted by geologists, such as W. W. Mather, a geologist working for the State of New York, for its unusual exposed bedrock. Because of its reputation, Rosendale cement was used as both a trade name and as a generic term referring to any natural hydraulic cement in the US. It was used in the construction of many of the

At the same time, the
American Society of Testing Engineers changed their standards to favor Portland cement, which was generally perceived as more consistent and with a much shorter drying time. By 1910, production dropped from a high of 8.5 million barrels a year to 1 million barrels a year, and by 1920 there was only one factory still in operation, that of A.J. Snyder. One revival of the industry occurred in the mid 20th century, when A.J. Snyder began to experiment by combining natural cement with Portland cement after New York State engineers noticed the durability of Rosendale cement. Notable structures built out of this hybrid are New York’s

Judge Lucas
Elemdorf picked up cement manufacturing in Lawrenceville, a hamlet of Rosendale, grinding the cement on the property of Jacob Low Snyder around 1827. Soon, several cement works were founded most notably by Watson E. Lawrence, of whom Lawrenceville is named, the aforementioned Canvass White, and his brother Hugh White, who founded Whiteport, a hamlet in Rosendale. Another notable cement plant was located in Binnewater, a hamlet of Rosendale, run by F. O. Norton, in about 1868, and another by A. J. Snyder on his own lands in Lawrenceville in 1850.

Portland cement, especially the horizontal rotary cylinder kiln, which decreased the cost significantly, while tripling output over previous kilns.

According to
Dietrich Werner, the former president of the Century House Historical Society, the proximity of the Rosendale region to the Delaware and Hudson Canal enabled the production and shipment of the natural cement. Soon, Rosendale cement could be found in all major American east coast ports

While the natural cement industry declined in the early 20th century, demand was later revived by efforts to restore historic buildings and structures using historically accurate materials. This led to the re-opening in 2004 of the historic
Hickory Bush Quarry in Rosendale, New York, operated by

in the late 1950s and early 1960s. Various writers, including Uriah
Cummings, appear to support the anecdotal evidence that Rosendale cement was highly durable, and with tensile strength equal to or greater than Portland, however the decline in the industry was unstoppable.
