ASTM C1385/C1385M-10

Standard Practice for Sampling Materials for Shotcrete

SIGNIFICANCE AND USE
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 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.
