Test No. 1
Test name: Specific gravity of cement.
Introduction:
Specific gravity of cement is the ratio of the mass of a given volume of the cement to that of
an equal volume of water at the same condition of temperature. The specific gravity of
Portland cement is generally about (3.12-3.19). Cement will react with water, so to prevent
this reaction kerosene should be used instead of water to be mixed with cement.
Purpose:
To find the specific gravity of cement.
Materials:
1- Ordinary Portland cement.
2- Water.
3- Kerosene.
Apparatus:
1- Pycnometer.
2- Weighing balance with sensitivity at least 0.1 gram.
3- Scoop.
