3. 1. INTRODUCTION
• Important to meet performance and durability requirements.
• Must be undertaken for a reasonable period of time as hydration of
cement take time.
• During preparation of concrete product or when placed in position.

4. 2. CURING
• Maintaining an adequate moisture content in concrete
during its early stages.
• Promoting hydration in cement.
• Controlling temperature.
• Controlling wind speed.
• Controlling relative humidity of surrounding air.
• Obtaining desired property of concrete.

8. 3. REASON FOR CURING
• Strong influence on properties of hardened concrete.
• Resistance to abrasion is increased .
• Shrinkage and cracks are reduced.
• Permeability and durability are increased.
• Demand for high quality concrete is increasing.
• All round improvement in quality of concrete.

• Materials used.
• Method of construction and economics.
• Intended use of the hardened concrete.
• Availability of materials, size, shape, and production facilities.

11. Curing Methods
A. Supply additional water with:
 Ponding or immersion
 Spraying or fogging
 Saturated wet coverings

12. Curing Methods
B. Membrane Curing:
 Satisfactory state of
wetness.
 Plastic sheets as a moisture
barrier.

13. 5. CONCLUSION
• The strength and durability of concrete will be fully developed only if it is cured.
• In India, curing is not a schedule item and so no rate is assigned for it. Hence if there
budget is allotted for curing work and volume of water used then contractor would the
work seriously. So, strength and durability of concrete will increase.
