ASTM C1602/C1602M-22

Standard Specification for Mixing Water Used in the Production of Hydraulic Cement Concrete

ABSTRACT
This specification covers mixing water used in the production of hydraulic cement concrete. It defines sources of water and provides requirements and testing frequencies for qualifying individual or combined water sources. Mixing water shall consist of: batch water, ice, water added by truck operator, free moisture on the aggregates, and water introduced in the form of admixtures. Potable and non-potable water is permitted to be used as mixing water in concrete. The following are concrete performance requirements for mixing water: compressive strength and time of set. Density of water shall be tested or monitored with a hydrometer. Optional chemical limits for combined mixing water are given for: chloride, sulfate, alkalis, and total solids.
SCOPE
1.1 This specification covers the compositional and performance requirements for water used as mixing water in hydraulic cement concrete. It defines sources of water and provides requirements and testing frequencies for qualifying individual or combined water sources. In any case where the requirements of the purchaser differ from these in this specification, the purchaser’s specification shall govern.  
1.2 This specification does not purport to cover methods of storage, transportation, or blending of water, or to address the development and maintenance of quality control programs sponsored or managed by the manufacturer.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.5 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.  
1.6 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 C1602/C1602M-22 is the internationally recognized standard specification for mixing water used in the production of hydraulic cement concrete. Developed by ASTM International, this standard outlines compositional and performance requirements for all water sources used in concrete production. Ensuring the quality of mixing water is critical in achieving consistent concrete performance, durability, and safety in construction projects. The specification covers both potable (fit for human consumption) and non-potable water, providing detailed guidelines for testing, qualification, and use of various water sources, including recycled and combined waters.

Key Topics

• Water Sources Covered:

  • Batch water (metered or weighed at the plant)
  • Ice
  • Water added by truck operators
  • Free moisture on aggregates
  • Water in admixtures (if it increases water-cementitious ratio by more than 0.01)
  • Potable and non-potable water
  • Water recovered from concrete production operations

• Performance and Compositional Requirements:

  • Compressive strength and time of set for concrete
  • Optional chemical limits for chloride, sulfate, alkalis, and total solids
  • Density testing with hydrometers for recycled water

• Testing and Documentation:

  • Frequency and methodology for qualifying water sources
  • Use of control (potable water) and test batches to verify compliance
  • Requirement to test non-potable or recycled water sources before use and at prescribed intervals

• Standards Compliance:

  • Adherence to specified units (SI or inch-pound)
  • Proper documentation and record-keeping for all test results and analyses

Applications

This standard is essential for:

• Concrete Producers: Ensuring that all water used in ready-mixed or precast concrete meets defined quality criteria, including when using alternative sources such as reclaimed or recycled water.
• Construction Quality Control: Providing a framework for verifying that concrete mixing water does not adversely impact strength, setting time, or durability of concrete structures.
• Project Specifications: Serving as a reference for project owners, engineers, and contractors to stipulate or verify water quality in contract documents for buildings, bridges, pavements, or other infrastructure.
• Sustainability Initiatives: Facilitating the use of recycled water in concrete while safeguarding performance, contributing to sustainable construction practices.
• Regulatory Compliance: Meeting building code requirements (such as ACI 318) and mitigating the risk of non-compliance in both public and private sector projects.

Related Standards

To ensure complete compliance and compatibility with industry best practices, users of ASTM C1602/C1602M‑22 should be aware of the following related standards:

• ASTM C31/C31M: Practice for Making and Curing Concrete Test Specimens in the Field
• ASTM C33/C33M: Specification for Concrete Aggregates
• ASTM C39/C39M: Test Method for Compressive Strength of Cylindrical Concrete Specimens
• ASTM C94/C94M: Specification for Ready-Mixed Concrete

• ASTM C125: Terminology Relating to Concrete and Concrete Aggregates
• ASTM C1603: Test Method for Measurement of Solids in Water
• American Concrete Institute (ACI) 318: Building Code Requirements for Structural Concrete

By following ASTM C1602/C1602M-22, concrete producers and construction professionals can ensure the integrity and quality of hydraulic cement concrete, supporting the durability and safety of structures while enabling flexible, sustainable use of available water resources.
