ASTM C1364-23

Standard Specification for Architectural Cast Stone

ABSTRACT
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.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
