Aggregate Specific Gravity & Absorption Test Equipment
Choose Fine- or Coarse-Aggregate Equipment
Aggregate specific gravity describes relative density, while absorption describes water taken into aggregate pores under the specified conditioning procedure. Begin with the material fraction and required method: fine-aggregate pycnometer measurements and coarse-aggregate suspended weighing use different equipment arrangements.
Specific gravity is not center of gravity, and its value alone does not establish aggregate strength or durability. Use the required test results alongside the other material properties specified for the project, without substituting a general density calculation for the governing method.
Build the Fine-Aggregate Setup
The Specific Gravity and Absorption of Fine Aggregate Set includes a pycnometer jar and brass top, conical mold and tamper. Match the equipment to the required preparation and saturated surface-dry assessment, following the method rather than an abbreviated product-page procedure.
For replacement components, compare the Conical Mold and Tamper for Fine Aggregate with what your laboratory already has. Confirm the balance, conditioning equipment and temperature measurement needed in addition to the supplied set. A kit title does not establish that every supporting laboratory item is included.
Specify Coarse-Aggregate Immersion Weighing
The Coarse Aggregate Specific Gravity and Absorption Set pairs a wire basket with a water container for submerged weighing. Verify the basket dimensions, specimen requirements and suspension arrangement before ordering. The basket must move freely without resting against the container during measurement.
For a bench-based installation, compare the Specific Gravity Bench for Weighing Samples and 30-Gallon Specific Gravity Water Tank. Check balance fit, weigh-below capability, specimen clearance and tank support as one system rather than choosing each component independently.
Match Accessories and Conditioning Equipment
The No.8 Stainless Steel Wire Mesh Basket is a separately listed component. Confirm the required container, suspension hardware and capacity for the intended test; not every basket or cradle in the wider category suits every specimen.
Identify which balance, water-temperature controls and drying equipment must be supplied separately. Follow the governing procedure for soaking, surface-dry preparation, drying and temperature. Do not replace those steps with a single universal calculation or assume a tank heater is included with a bench.
Keep Aggregate and Asphalt Methods Distinct
Maximum specific gravity testing of loose asphalt mixtures uses a different setup; review asphalt Rice test equipment for that task. Binder bottles and other asphalt-gravity arrangements are covered in specific gravity equipment for asphalt.
Before completing an aggregate order, check the full equipment list against the required method, including calibration documentation and replacement seals or suspension components. Confirm compatibility of shared accessories without treating the aggregate and asphalt procedures as interchangeable.
