ASTM C1385/C1385M-10(2017)
(Practice)Standard Practice for Sampling Materials for Shotcrete
General Information
- Abstract
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.

Overview
ASTM C1385/C1385M-10(2017): Standard Practice for Sampling Materials for Shotcrete provides essential procedures for obtaining representative samples of materials intended for shotcrete application. Developed by ASTM International, this practice ensures that materials delivered to the shotcrete machine are properly sampled, enabling accurate testing and evaluation for compliance with relevant specifications.
This standard applies to a range of delivery methods, including stationary and truck mixers, volumetric and continuous mixers, as well as bagged and bulk materials. By following ASTM C1385/C1385M, practitioners can help ensure the quality, consistency, and suitability of shotcrete materials in a variety of construction environments.
Key Topics
Representative Sampling Procedures
- Covers methods for selecting and obtaining samples from different equipment types and delivery forms, such as:
- Stationary and truck mixers
- Continuous and volumetric mixers
- Bagged and bulk shotcrete materials
Sample Size and Handling
- Specifies minimum sample sizes for both individual and composite samples to ensure reliable testing
- Details precautions and procedures to maintain the integrity and representativeness of samples throughout the sampling process
Sampling Timeframes
- Outlines time limits and procedures for obtaining and testing wet and dry process shotcrete samples to avoid material variability
Units of Measurement
- Provides guidelines for the use of inch-pound and SI units in reporting and conducting sampling procedures
- Stipulates that combining measurement systems is not permissible to avoid nonconformance
Safety and Compliance
- Highlights the requirement for users to establish suitable safety, health, and environmental practices
- Advises users to adhere to regulatory restrictions and best practices when applying this standard
Applications
Construction Quality Assurance
- Used to sample materials for quality control and to verify compliance with mix design specifications before shotcrete application
- Ensures that delivered materials are consistent with job requirements through representative sampling and subsequent testing
Infrastructure and Civil Projects
- Ideal for use in tunnels, retaining walls, slope stabilization, and other structures utilizing shotcrete
- Supports compliance verification for contractors, material suppliers, and quality assurance personnel
Testing and Inspection
- Guides laboratory and field personnel in obtaining and preparing samples for physical and chemical testing
- Facilitates routine assessment of material properties, such as consistency, composition, and suitability for shotcrete operations
