Astm D 4373 Updated (HOT)

The method relies on the chemical reaction between carbonates present in the soil and hydrochloric acid (HCl). The reaction produces carbon dioxide (CO₂) gas.

This test method covers the quantitative determination of the carbonate content (primarily calcium carbonate, CaCO₃) in soils, using a gasometric method. It is suitable for both fine-grained and coarse-grained soils, as well as soft rock and aggregate materials. astm d 4373
