Specific Gravity of Aggregate

Specific Gravity, or relative density of materials, is an important property used in many calculations for mix design, proportioning, bulk density, absorption, and void content of aggregates and other construction materials. Gilson’s exclusive Specific Gravity equipment yields accurate, repeatable results and meets ASTM C127/128 specifications.

  • Rice Shaker is a deairing device that offers consistent, automatic agitation of vacuum pycnometers for specific gravity tests of fine aggregates and soils.
  • AutoRiceTM Digital Manometer/Controller offers precise regulation of vacuum pressure and time, and monitoring of shaker vibration energy during Rice Testing.
  • Digital Residual Pressure Manometer comes in either a traditional Mercury-based or a mercury-free digital option and provides vacuum level readings.
  • Vacuum Pycnometers are available in three diverse options for specific gravity determinations including 2,000g and 6,000g Pycnometers, as well as Heavy-Wall Glass Filter Flasks.
  • Flasks are available for the specific gravity testing of cement, soils, aggregate, bitumen, pitch, and other materials.
  • Vacuum Pumps range from small to heavy-duty models for specific gravity tests.
  • Drierite Air/Gas Drying Unitis an in-line device to effectively protect vacuum pumps from moisture when deairing test specimens.
  • Indicating Drierite is used in conjunction with the Laboratory Air/Gas Dryer and for other applications to quickly absorb water vapor from air and gases.
  • Specific Gravity Bench is the best solution for weighing suspended samples in water for specific gravity measurements of aggregates, hardened concrete, bituminous mixtures, and many other materials.
  • Specific Gravity Water Tanks have a 30gal or 44gal capacity and are equipped with drain and overflow outlets. The 44gal tank is preferred for ASTM D2041 and AASHTO T 209 tests.
  • Density Weighing Cradles of stainless steel secures solid specimens when weighing and holds standard Vacuum Pycnometer Canisters or Aggregate Density Baskets.
  • EZ Mount Heater/Circulator is portable, compact, and has the mounting capability to effectively maintain tap water in immersion weighing tanks to the required temperature for specific gravity tests.
  • Heater/Circulator with 1,100 Watt heating capacity accurately controls temperature from ambient + 9° to 302° ±0.09°F (ambient + 5° to 150° ±0.05C) for baths and water tanks up to 7.4gal.
  • Specific Gravity & Absorption of Fine Aggregate Set is an all-in-one solution with all the components you need for the test including a pycnometer jar with a top, conical mold, and tamper.
  • Specific Gravity & Absorption of Coarse Aggregate set has a Wire Basket and a Polyethylene Container, all the necessary components to perform the test.
  • Vibra Pad serves as an agitator and a light-duty shaker for deairing applications.
