Wet Cure Concrete 3

[RFreund]

I received a question from a contractor asking to wet cure a slab on grade. However, they wanted to use Visqueen in lieu of burlap. They propose to soak the slab and cover it in visqueen for 5 days. There are no cure and seal products being used for this slab.

I had a few questions:

1. Does this seem like a possible option? My first questions is how/when would they "soak" the slab.
2. When/how are control joints made when you wet cure a slab?
3. Any reference material you could point me towards? Normally I would expect burlap to be wetted for about 7-14 days but the control joints need to be placed within a day.

Thanks!

Thanks for that, DamsInc. I might have read that at one time, but forgot. So basically that source is saying that no matter what is done in sealing the surface, complete curing cannot be accomplished in low w/c concrete.

Right. Incomplete hydration happens for all w/c, but even more for low w/c. But for concrete that isn't exposed to harsh conditions, that's ok because the lower amount of hydration achieved with just sealing the concrete is all that's needed to achieve the desired strength.
