Hydraulic Cement Characteristics

The characteristics of hydraulic cement are –

  • Hydraulic Cement sets extremely fast and hardens with good strength after it has been mixed with water. It hardens within three minutes after a chemical reaction with the mixing water.
  • This cement is cost effective.
  • Very easy to use.
  • Hot water accelerates the setting time while cold water retards the setting time of cement.
  • Hydraulic Cement is very strong and works very well even when submerged in water. Hence it is widely used in structures that are submerged in water.
  • It does not corrode or get rusted.
  • Hydraulic cement expands when dried.

It is widely used in swimming pools , foundations , sealing around concrete pipes ,drainage systems, manholes , marine applications , elevator pits to name a few. It is also used as a repair material used to block cracks.
