History of Cast Stone
Cast Stone is a venerable building material that is at it's heart, concrete. Concrete is a versatile mixture of portland cement along with various sized aggregates in a carefully choreographed mixture designed to produce a wide range of strength and durability attributes in the finished material. The site caststone.org is a great source of historical, structural and usage information.
The earliest known use of Cast Stone dates about to the year 1138 at Carcassonne, France, which contains the finest remains of medieval fortification in Europe. Cast Stone was used extensively in London in the year 1900 and gained widespread acceptance in America in 1920. Today, Cast Stone is a truly superior alternative to natural cut building stone and is used for its beauty, permanence and tremendous versatility.
