Full title and description
ASTM C1603-23 — Standard Test Method for Measurement of Solids in Water. Defines a laboratory procedure to determine the solids content of water used as mixing water for hydraulic-cement concrete (expressed in parts per million or percent by mass) and describes a practical density-based measurement technique and correlation procedure for use in production and quality control.
Abstract
This test method provides a quick, reproducible means to measure solids present in mixing water (including wash or recycled water) and to relate measured water density to solids concentration. The procedure supports compliance with solids limits in mixing-water specifications (for example ASTM C1602/C1602M) and is intended for field and laboratory use at ready-mix plants and testing laboratories. The standard specifies required apparatus, sample preparation, measurement steps, and means to develop a density–solids correlation for production use.

Scope
ASTM C1603-23 covers measurement of solids content in water intended for use as mixing water in ready-mixed concrete and measurement of the water’s density. Solids content is reported as parts per million (ppm) or percent by mass of the sample. The method is applicable when one or more water sources contain suspended solids (for example wash water or recycled process water) and provides procedures to develop density–solids correlations for production control and specification compliance. The standard references related terminology and other ASTM test methods as needed.
Key topics and requirements
- Definition of solids content reporting (ppm or percent by mass).
- Measurement of water density using a defined density measure (minimum volume ~200 mL) and procedure to determine volume accurately.
- Sample drying or solids determination procedure (laboratory drying or equivalent) to establish solids mass for correlation.
- Procedure to develop and use a density-to-solids correlation covering the expected production range.
- Apparatus requirements (density measure, glass or hard-plastic plate, microwave oven of adequate power or laboratory drying oven, balances, etc.).
- Reference to related terminology (ASTM C125) and precision/bias guidance (ASTM C670 where applicable).
- Use of results for compliance with mixing-water specifications such as ASTM C1602/C1602M.
Typical use and users
Used by ready-mixed concrete producers, plant quality-control technicians, independent testing laboratories, materials engineers, and specifiers who need to verify and document solids content in mixing water—especially when using wash or recycled water sources. Also used by researchers and regulatory bodies assessing recycled-water suitability for concrete production.
