ASTM C114-24 PDF

Full title and description

ASTM C114-24 — Standard Test Methods for Chemical Analysis of Hydraulic Cement. This standard provides reference and alternative wet-chemical and instrumental procedures for determining the chemical composition of hydraulic cements, including major oxides, loss on ignition, sulfur, chlorides, and selected minor constituents used for certification, referee, and routine quality-control analyses.

Abstract

These test methods cover the chemical analyses of hydraulic cements by presenting a set of reference (classical) procedures and alternative methods for individual constituents. The standard defines required reagents and apparatus, sample preparation and general procedures, reporting order (major, minor, separate determinations), and specific determinations such as silicon dioxide, aluminum oxide, ferric oxide, calcium oxide, magnesium oxide, sulfur, chloride, loss on ignition and others. SI units are the standard units for the document.

General information

• Status: Active standard.
• Publication date: January 6, 2024 (designation: C114-24).
• Publisher: ASTM International.
• ICS / categories: 91.100.10 — Cement (cement, gypsum, lime, mortar).
• Edition / version: C114-24 (current edition, DOI: 10.1520/C0114-24).
• Number of pages: 32 pages.

Scope

Provides standardized test methods for the chemical analysis of hydraulic cements. Methods are presented as Reference Test Methods (classical integrated chemical analyses used for referee purposes) and Alternative Test Methods (individual determinations or alternate procedures). The scope covers sample preparation, required apparatus and reagents, procedural details for individual constituents, calculation and reporting, and precision/limitations. The standard is intended for use where accurate compositional data are required for specification compliance, certification, or research.

Key topics and requirements

• Classification of methods into Reference Test Methods and Alternative Test Methods.
• Determination procedures for insoluble residue, SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, TiO2, P2O5, MnO, ZnO, chlorides, and organic impurities.
• Loss on ignition (LOI) procedures and special LOI notes for blended cements (e.g., blast-furnace slag cement).
• Requirements for reagents, apparatus (balances, crucibles, muffle furnace, glassware), and laboratory practice for reliable results.
• Reporting order and format: major components first, minor components, then separate determinations; SI units as the standard.
• Use of validated curve-fitting and standardization procedures for quantitative determinations and referee analyses.

Typical use and users

Used by cement manufacturers, quality-control and materials testing laboratories, standards bodies, construction materials researchers, and regulatory or certification agencies. Typical applications include routine plant QC, certification and referee analyses when specification conformance is disputed, product development, and laboratory intercomparisons.

Related standards

Commonly used alongside product and sampling specifications and test standards for cement and concrete, for example ASTM C150 (Specification for Portland Cement), ASTM C595/C1157 (blended and performance cements), and sampling/handling standards such as ASTM C311. Users often apply C114 results in conjunction with physical and performance standards to assess overall cement suitability. (Note: consult the latest editions of related ASTM specifications for harmonization and referencing requirements.)

FAQ

Q: What is this standard?

A: ASTM C114-24 is the ASTM International standard titled "Standard Test Methods for Chemical Analysis of Hydraulic Cement." It specifies chemical analysis procedures for hydraulic cements, including reference and alternative methods for determining major and minor constituents.

Q: What does it cover?

A: It covers sample preparation, required laboratory equipment and reagents, step-by-step analytical procedures (e.g., determinations for SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, chlorides, LOI), reporting conventions, and the classification of methods into reference and alternative procedures. SI units are the standard units used.

Q: Who typically uses it?

A: Cement producers, quality-control and independent testing laboratories, standards committees, materials researchers, and certification/referee laboratories that require authoritative chemical composition data for specification compliance or dispute resolution.

Q: Is it current or superseded?

A: As of the C114-24 designation (published January 6, 2024) the standard is active. ASTM continues routine oversight and work items for revisions; a work item to revise C114 was recorded in early 2026, indicating ongoing maintenance and potential future updates. Users should check ASTM communications for amendment or revision ballots when preparing formal compliance documentation.

Q: Is it part of a series?

A: C114 is part of the ASTM C01 committee portfolio covering cement and concrete-related standards and is often used in conjunction with other ASTM cement specifications and testing standards (e.g., C150, C595, C1157, C311) to provide a complete materials characterization and compliance framework.

Q: What are the key keywords?

A: Chemical analysis, hydraulic cement, compositional analysis, loss on ignition, calcium oxide, silicon dioxide, chloride, sulfur, reference methods, alternative methods.
