1、Designation: C 1436 99 (Reapproved 2004)Standard 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 numb

2、er in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers materials for use in hydraulic-cement concrete mixtures to be placed by shotcreting. It doesnot cover mixing, pl

3、acement, curing, or 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 as thestandard.1.4 This standard does not purport to address all of thesafety concerns, if any, ass

4、ociated 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.

7、general specifi-cations, the purchaser shall include the following informationin the purchase contract or order, if applicable:4.1.1 The specification designation and date of issue,4.1.2 Specification for cement and type (see 5.1.1),4.1.3 Grading number for total combined aggregates re-quired (see 5

8、.1.2),4.1.4 Specification, type, and grade(s) for admixtures re-quired (see 5.1.4), and4.1.5 Specification, type, length, and, if appropriate, thediameter (or equivalent cross-sectional dimensions) of fiberrequired (see 5.1.5).5. Material Requirements5.1 In the absence of designated applicable speci

9、ficationscovering requirements for quality of materials, the followingrequirements shall govern:5.1.1 CementCement shall be in accordance with Speci-fication C 150, Specification C 595, or Performance Specifica-tion C 1157. If special properties are required, the purchasershall limit the choice of c

10、ements to those suitable for thespecial use.5.1.2 AggregatesAggregates shall be in accordance withSpecification C 33 or Specification C 330 if lightweight shot-crete is specified by the purchaser except that the grading of thetotal aggregate constituent of the shotcrete shall be in accor-dance with

11、the requirements prescribed in Table 1 for thegrading number specified.NOTE 1The ranges shown in Table 1 are by necessity wide in order toaccommodate nationwide conditions. For quality control of any specificoperation, a producer should develop an average grading for the particularsource and product

12、ion facilities, and control the grading within reasonabletolerances from this average.5.1.3 WaterThe mixing water shall be in accordance withthe requirements for water prescribed in Specification C 1116.5.1.4 AdmixturesMineral and chemical admixtures shallbe in accordance with Specification C 1141.5

13、.1.5 FibersFibers shall be in accordance with the re-quirements for fibers prescribed in Specification C 1116.1This specification is under the jurisdiction of Committee C09 on Concrete andConcrete Aggregates and is the direct responsibility of Subcommittee C09.46 onShotcrete.Current edition approved
