1. Apply a membrane-curing compound-eithe r by spraying or rolling on the surface immediately after the troweling process on slabs has ceased, or on walls, columns, beams, after the forms have been removed.
2. Curing by water in other than cold-weather conditions is acceptable, as long as it is continuous.
3. Waterproof paper, applied directly over the concrete surface after it has received a spray of water, is often effective.
4. Damp burlap, free of foreign substances that could leach out and stain the concrete, is also a proven curing procedure, as long as the burlap is kept moist.
5. Polyethylene sheets can be used as a blanket in much the same manner as waterproof paper, as long as its edges are lapped and sealed properly.
6. Damp sand or straw is also used on occasion, when nothing else is available. These materials must also be sprayed from time to time to maintain the moisture content.
The length of curing depends upon a number of factors, including the type of cement used and am bient temperatures. The following can be used as a guideline to determine the length of curing time.

This is just the information I was looking for about concrete curing. I have a friend who is working in construction right now. The other day he told me that he was going to work on his first concrete curing job. I didn't know what that was so I decided to do some research. Explaining the process in this article helped me understand more of what my friend does at work. I will have to tell him what I learned!
