Cast Stone is defined as “a refined architectural concrete building unit manufactured to simulate natural cut stone, used in unit masonry applications and is manufactured to meet Division 04 72 00 requirements. Used as an architectural feature, trim, ornament or facing for buildings or other structures, it is created with a fine grain texture to simulate all types of natural cut stone including but not limited to limestone, granite, slate, travertine or marble.
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 while maintaining durable physical properties which exceed most natural cut building stones.
Cast stone is generally built into a load bearing masonry wall system in traditional commercial and residential buildings and other structures. It is specified as per ASTM C1364, Standard Specification for Architectural Cast Stone that was originally approved in 1997.
