Cast stone or reconstructed stone is a concrete masonry form of artificial stone which simulates natural-cut stone. It is used for architectural features, trim, or ornament, facades of buildings or other structures, statuary and for garden ornaments. It is also used for features such as step units, pier caps and copings.
Cast stone can be made from white and/or grey cements, manufactured or natural sands, crushed stone or natural gravels, and coloured with mineral colouring pigments.
Cast stone may replace such common natural building stones as limestone, brownstone, sandstone, bluestone, granite, slate, coral, and travertine.
