1、Designation: C 1436 08Standard Specification forMaterials for Shotcrete1This standard is issued under the fixed designation C 1436; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses

2、indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers materials for use in hydraulic-cement concrete mixtures to be placed by shotcreting. It doesnot cover mixing, placement, curing, o

3、r protection of theconcrete placed by shotcreting.1.2 This specification covers materials for both wet-mix anddry-mix shotcreting.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This standard does not purport to address

4、all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of the standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
