GB/T 208-2014 is a recommended Chinese national standard that describes a laboratory method for determining the density of cement (and similar powders) using a displacement approach.

GB/T 208-2014 — Test method for determinging cement density
This standard is used when cement density is needed for materials control, mix design inputs, technical documentation, or comparison of cement lots and types.
GB/T 208 is typically applied in cement and concrete laboratories, quality control departments at cement producers, and construction materials testing labs.
Quick Definition
Document type: Test method.
Measured property: Density of cement (mass per unit volume) determined by liquid displacement.
Typical outcome: A reported cement density value used as an input to downstream calculations (for example, mix proportioning and yield-related checks).
What This Standard Covers
GB/T 208-2014 describes a displacement-based method for determining cement density by introducing a known mass of cement into a calibrated vessel containing a suitable liquid medium and using the displaced volume to calculate density.
The method is intended for cement and can also be used for other powdered materials when this displacement approach is appropriate and the liquid medium does not react with the material.
Why This Standard Matters in Testing
Cement density is frequently used as a basic material property for production control and for calculations where cement volume is needed (rather than only mass). A consistent density method helps reduce variability when comparing results between suppliers, sites, or labs.
Because the result depends on the vessel calibration and the liquid medium behavior, repeatability is strongly influenced by equipment condition, technique, and temperature control.
Common Materials, Product Types, or Applications Covered
Common materials: Portland cement and similar cementitious powders; other powders where a non-reactive displacement liquid can be used.
Common use cases: Cement plant QA/QC, third-party cement acceptance testing, and concrete mix design support where a cement density value is required.
Common Test or Verification Workflow
Most labs apply GB/T 208 within a routine physical-testing workflow alongside other cement characterization tests. A typical sequence includes preparing the liquid medium, recording initial readings on the calibrated vessel, introducing a known cement mass, allowing entrapped air to dissipate as required by the method, and calculating density from the mass and displaced volume.
Practical caution: The choice and condition of the displacement liquid, glassware cleanliness, and stable temperature conditions can materially affect readings. When results are used for contractual or compliance purposes, match the exact edition and any referenced documents cited in the purchasing or project requirements.
Equipment Commonly Used for This Standard
GB/T 208 is equipment-light compared with strength testing methods, but it is technique-sensitive and benefits from consistent lab tools.
Common equipment: A calibrated displacement flask/vessel used for cement density determination (often referred to as a Le Chatelier-type flask), a suitable laboratory balance for mass measurement, a thermometer or temperature-measurement approach for stable readings, and accessories for careful powder handling and cleaning.
For labs standardizing cement density reporting across multiple sites, it is usually worth aligning vessel type, balance resolution, and temperature practices before purchasing duplicate sets of equipment.
How to Read This Designation or Revision
GB/T: Identifies a recommended (not mandatory) national standard of the People’s Republic of China.
208: The base standard number.
-2014: The publication year for this edition. When a specification or contract cites “GB/T 208” without the year, confirm whether the 2014 edition is intended or whether an older edition is being referenced.
Related Standards, Methods, or Frameworks
GB/T 208 is commonly used alongside broader cement and concrete test programs where density values support mix proportioning, yield checks, and comparison of cement types. In many laboratories, the density test is managed as part of a larger cement physical-properties workflow rather than as a standalone compliance activity.
