Title: Curing Concrete


1
Curing Concrete
2
Curing
Curing requires adequate
  • Moisture
  • Temperature
  • Time

If any of these factors are neglected, the
desiredproperties will not develop
3
Effect of Adequate Curing on Hardened Concrete
  • Increased
  • Strength
  • Watertightness
  • Abrasion resistance
  • Freeze-thaw resistance
  • Volume stability

4
Effect of Moist Curing
5
Effect of Curing Temperature on Strength
6
Effect of Curing Temperature on Strength
7
Curing Methods
  • 1. Supply additional water with
  • Ponding or immersion
  • Spraying or fogging
  • Saturated wet coverings

Curing of Concrete by Supplying Water
Evaporation from water surface
Water supplied from external source

Curing Methods
  • 2. Seal in mixing water
  • Plastic sheets
  • Membrane-forming curing compounds

Curing Methods
  • 3. Strength gain is accelerated with
  • Live steam
  • Heating coils
  • Electrically heated forms or pads
