This standard details the procedure for determining the density (specific gravity) of hydraulic cement using a Le Chatelier flask and a non-reactive liquid like kerosene or naphtha.
Describes the procedure for determining the density (unit weight) of hydraulic cement.
Quick Reference Values
standard test temperature27 ± 2 °C
standard weight of cement64 g
minimum density of liquid (kerosene/naphtha)0.73 g/ml at 27 °C
Key Formulas
Density = Mass of cement (g) / [Final volume reading (V2) - Initial volume reading (V1)] (cm³)
Practical Notes
Ensure the kerosene or naphtha used is completely free of water to prevent cement hydration during the test.
The Le Chatelier flask must be kept in a constant temperature water bath to avoid volume fluctuations caused by thermal expansion or contraction of the liquid.
Air bubbles must be completely removed by gently rolling the flask in an inclined position before taking the final volume reading.
