Answering this question first requires that we define "natural cement". The current definition (ASTM C219) is hydraulic cement produced by calcining argillaceous limestone at temperatures below the sintering point and grinding to a fine powder.
Under this definition, the first natural cement would have been Parker's Roman Cement, patented in Great Britain in 1796. The first natural cement production in North America is generally attributed to Canvass White in 1819, in Fayetteville, NY. This cement was used in the construction of the Erie Canal, and the subsequent development of other natural cement production sites often coincided with the building of canal systems, including major sites along the Ohio and Potomac Rivers, the Great Lakes and others.

Is cement a natural material?
Cement is a man-made material produced by heating and grinding together a mixture of limestone and clay. It is not generally considered a natural material due to the extensive human processing involved in its production.
Who produced the first high quality cement?
John Smeaton in 1756 used the first high quality cement to builkd thge Eddystone lighthouse in England
How is cement extracted?
Cement is produced by extracting limestone, clay, or sandstone from quarries. These raw materials are crushed and heated at high temperatures in a kiln to form a substance called clinker. The clinker is then ground into a fine powder and mixed with gypsum to create cement.
Is concrete man made or a natural resource?
Concrete is a man-made material that is produced by mixing cement with aggregates and water. It is not a natural resource, but rather a construction material that is widely used for building structures.
What is the area of Snyder Estate Natural Cement Historic District?
The area of Snyder Estate Natural Cement Historic District is 1,112,885.51616 square meters.
Is cement natural?
Cement is not natural in its raw form. It is a manufactured product made by heating limestone and other materials at high temperatures to create a powdered substance that forms the basis for concrete when mixed with water, sand, and gravel.
Is concrete natural?
Concrete is not considered natural as it is a man-made material produced by mixing cement, water, and aggregates like sand and gravel. It undergoes a chemical reaction, called hydration, that causes it to harden and set.
How does natural cement form?
Natural cement forms through the natural process of hydraulic binding, where calcium carbonate in limestone gets transformed into calcium oxide upon heating. The resulting calcium oxide reacts with water to form calcium hydroxide, which then combines with silicates and aluminates in the presence of water to create a hydraulic binder, known as natural cement.
Is cement a man made of natural resource?
