  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

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

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

  10. Membrane Curing of Concrete Evaporation from water surface Curing membrane Partially saturated Saturated Concrete

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

  12. Steam Curing

  13. Strength vs. Steam Curing

  14. Strength vs. Curing Temperature

  15. Sealing Compounds
