ASTM C1385/C1385M-10(2017)
(Practice)Standard Practice for Sampling Materials for Shotcrete
Standard Practice for Sampling Materials for Shotcrete
SIGNIFICANCE AND USE
4.1 This practice is used to obtain representative samples of materials delivered to the shotcrete machine. These samples are used to perform tests to determine compliance with the specifications under which the material is furnished.
SCOPE
1.1 This practice covers procedures for obtaining representative samples of materials to be shotcreted. The practice covers sampling from stationary and truck mixers, volumetric and continuous mixing equipment, and bag and bulk delivery.
1.2 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this practice.
1.3 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.
1.4 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.
