I fabricate concrete countertops. Recently, I have had a little problem with slab curl. Most of it I attributed to colder weather as our wharehouse temp dropped. I also question if the accellerator in our admix may have caused some of this.

So, what are the primary causes of slab curl (thin slabs 1.5 to 2 inches) and what are the best ways to solve these problems?

Curl is caused by inconsistent curing over the body of the structure, especially near the edges or saw cuts. Cold weather shouldn't be considered a factor in curling. The slower and more thorough the cure, the less chance you have of curling. Just make sure all surfaces have an equal amount of moisture and temperature and that should get rid of that pesky curling.
Concrete is good.
