Cast Stone Institute
Standard Specification 04720-19
This specification encompasses basic requirements for Cast Stone, a building stone manufactured from a mixture of Portland cement and carefully graded clean 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.
Materials and processes used for manufacturing Cast Stone vary widely according to the aggregates locally available to the manufacturers and the processes and techniques used by the manufacturers to obtain the desired appearance and physical properties. Of paramount importance in molding Cast Stone is the need to employ a properly proportioned mixture of white and/or grey cements, manufactured or natural sands, carefully selected crushed stone or well graded natural gravel and mineral coloring pigments to achieve the desired appearance while maintaining durable physical properties.
Although a variety of casting methods are used, production conforming to this standard will exceed minimum requirements for compressive strength and weathering qualities essential for normal installations as a suitable replacement for natural cut limestone, brownstone, sandstone, bluestone, granite, slate, keystone, travertine and other natural building stones.
It is hoped that this specification may be helpful to the specifiers in understanding the inherent qualities of Cast Stone and its use. For details and samples of finishes available in your project area, contact AHI Supply LP. 2800 N. Gordon, Alvin Texas
