ASTM C642-21 (the most recent version) outlines procedures to determine the mass-to-volume relationships within concrete. It is widely used for: The test determines concrete density in three distinct

The volume is determined by the difference between the mass in air and the mass in water. $$V = B - C$$ (Where $V$ is in the same units as mass, assuming density of water $\approx 1$ g/cm³). It is widely used for: The volume is

The dry specimen is immersed in water at approximately 21∘C21 raised to the composed with power C

To ensure accuracy, the following equipment is required:
