  • This test method covers the determination of carbonate (CaCO3) content of soils and soft rock which can be readily broken down by mechanical effort.
  • It is a gasometrical method that utilises a simple portable apparatus.
  • The test method is quickly performed for soils containing calcium carbonate.
  • The calcium carbonate content of soil is determined by treating a 1-g dried soil specimen with hydrochloric acid (HCl) in an enclosed reactor vessel.
  • Carbon dioxide gas is evolved during the reaction between the acid and carbonate fraction of the specimen.
  • This pressure is measured with a bourdon tube pressure gauge that is pre-calibrated with reagent grade calcium carbonate.
  • This test method is used to determine the presence and quantity of calcium carbonate on a marine soil specimen.
  • Calcium carbonates k known cementing agents, are water soluble at PH<7, and are soft on the Mohs’ scale compared to other soil minerals.
  • The acrylic chamber is 63.5mm internal diameter x 139.7mm long and sealed with anodised end caps. The unit comes complete with 10psi test gauge, bleed valve and a 20ml cup with handle.
  • Please refer to ASTM D-4373 for complete instructions on how to prepare and perform the test for determining the carbonate content of soils and soft rock.
  • The device is made from Stainless Steel with an acrylic chamber.
  • The pressure gauge can be damaged if the solution is allowed to flow into the gauge opening.
  • Keep in mind that when tilting to spill the acid, that care must be taken to prevent this acid from reaching into the pressure gauge opening.
  • Clean the device thoroughly after use.
