ASTM C1875

ASTM C1875 is the ASTM standard for determining major and minor elements in aqueous pore solutions of cementitious pastes by inductively coupled plasma optical emission spectroscopy (ICP-OES). It provides a structured approach for analyzing the ionic chemistry of pore solutions, which can support material evaluation, research, and quality-focused testing. For laboratories and technical teams working with cementitious materials, this standard helps create more consistent elemental measurements and clearer comparisons across samples.

What is ASTM C1875?

ASTM C1875 addresses a practice for measuring major and minor elements dissolved in the aqueous pore solutions of cementitious pastes using ICP-OES. The standard is centered on analytical testing rather than mix design or performance claims, and it helps define a repeatable framework for laboratory determination of elemental composition. In practical terms, it supports controlled analysis of pore solution chemistry, which can be useful when evaluating cementitious systems, comparing test results, or documenting material behavior under defined conditions.

Where is ASTM C1875 used?

ASTM C1875 is commonly used in laboratory and research environments that work with cementitious pastes and pore solution analysis. It is relevant where ICP-OES is used to determine elemental concentrations in extracted aqueous pore solutions, such as in materials testing, product development, and technical investigations. The standard may also support quality control programs or comparative studies where consistent chemical analysis is needed for cement-based systems and related construction materials.

Why is ASTM C1875 important?

ASTM C1875 is important because it helps standardize how pore solution chemistry is measured, which can improve consistency and comparability in testing. A common practice is valuable for compliance-oriented work, technical evaluation, and risk reduction when assessing cementitious pastes. By giving laboratories a recognized method for ICP-OES-based elemental determination, ASTM C1875 supports clearer data interpretation and more reliable decision-making in material assessment and quality control.
