Curing for Newly Constructed Wall, Slab and Concrete structure

The Curing is very important as the concrete attains its 58% strength in 7 days and 98% in 28 days. So water should be slugged at least for 7 days over the slabs and should be watched that it is not dried at any point of time, because it weakens the strength. For walls proper water curing should be done, at least three times a day. For pillars it should be covered with Gunny or strand and it should be always in wet condition.

• Curing helps to increase the strength of the wall.
• Durability of the concrete improves with curing.
• Curing helps in minimizing the cracks.
• It prevents shrinkage of brick walls during drying.
• Curing makes the walls water tight.

The Special care in straw curing should be taken while pipe lining is packed, by means of wire mesh and plastering as it will not be noticed by many people, which develop cracks.

Similarly curing after plastering is very essential, as it is the blood for strengthening the cement mortar. It should be done at least three times a day for a week and should ensure that the wall is wet & not dried at any point of time; most precaution should be taken care of, from the external wall curing, as it will get into dried easily.

It should be cured with softened water so that salt deposit will not form on the walls & Concretes.

When to Start Curing:

• Before plastering: The best time to start curing of brick walls is within 12 hours. The reason to wait for 12 hours is that the concrete mix takes at least 10 hours to set itself and you can start curing the wall after that period.
• After plastering: After the final stage of cement plastering is done, it is advised to start curing within 24 hours.
