Properties of Cement

The properties of Cement entirely depends upon its composition, burning and grinding. The important properties of good Cement are the following:-

  • Strength: The compressive strength of cubical blocks of ordinary Portland cement and sand (1:3) after 7 days should not less than 175 kg/cm2.
  • Finess : The quality of Cement depends upon its fineness property. So good Cement should be fine. The fineness of Cement may be determined by a sieve test. Also by touching the Cement, it may be checked and should be smooth.
  • Soundness: All types of cement expand to some extent and it depends upon the composition, proper burning, and grinding of Cement. A good quality Cement should not undergo a large change in volume after setting. Also, it should not crack or disintegrate after setting.



Some Following factors are also responsible for Properties of cement.

  • Consistency¬†
  • Setting time
  • Heat of hydration
  • Loss of ignition
  • Bulk density
  • Specific gravity (Relative density)

The main causes if volumetric change or unsoundness are:-

  • Excessive addition of gypsum
  • Excess of lime
  • Less burning
  • Excess of magnesia content.
  1. Presence of Lumps: By absorbing the moisture from the atmosphere the lumps are formed. A good Cement should be a frame from lumps. These can be avoided by storing the Cement away from damp places.
  2.  Colour : The colour of cement should be greenish grey. The colour indicates the degree of burning. e.g. A yellowish colour indicates poor burning.
  3. Resistance to moisture: The Cement should resist against moisture.
  4. Plasticity: A Cement should be plastic in nature.
