This specification establishes the physical requirements, sampling, testing, and visual inspection of architectural cast stone that may be made from facing and backup mixtures or from a homogeneous mixture, produced either by wet or dry casting. Conformances for raw materials, Portland cement, aggregates, coloring pigment, reinforcement, chemical admixtures, air entraining admixtures, water reducing and accelerating admixtures, ground slag, fly ash or natural pozzolan, and other consituents shall be precisely observed. Products shall also conform to specified physical and performance requirements such as compressive strength, cold water absorption, boiling water absorption, air content, field testing, resistance to freezing and thawing, and linear drying shrinkage.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification includes the physical properties, sampling, testing, tolerance, and appearance requirements for architectural cast stone.

1.2 Cast stone units covered under this specification include both wet cast and vibratory dry tamp products. Production methods of cast stone can vary among manufacturers; many production methods are acceptable provided the delivered cast stone meets the requirements of this specification.

1.3 Surface textures, finish, color, special applications, or other features shall be specified by the purchaser. Slump, manufacturing method, and apparatus shall be selected by the manufacturer and not specified by the purchaser.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
