Cast Stone Info
As defined by The Cast Stone Institute

Cast Stone is a highly refined architectural precast concrete building stone manufactured from a mixture of Portland cement and coarse and fine aggregates to simulate natural stone. Cast Stone is generally used as a masonry product, as an architectural feature, trim, ornament, or facing for buildings or other structures. Cast Stone can be made from white and/or grey cements, manufactured or natural sands, carefully selected crushed stone, or well-graded natural gravels and mineral coloring pigments to achieve the desired color and appearance and still maintain durable physical properties which exceed most natural cut building stones. Cast Stone is an excellent replacement for natural cut limestone, brownstone, sandstone, bluestone, granite, slate, keystone, travertine, and other natural building stones.
