How many days to allow contractor to take off forms from concrete wall
How many days to allow contractor to take off forms from concrete wall
(OP)
Hi guys,
I have a question need your help. About how many days do you allow a contractor to take away the form from a poured concrete foundation wall? The wall has no external load at all except its own weight, the contractor wants to take away the form the next day after the concrete is poured. Will it cause any problem? Any suggestion?
Thanks.

The only time I require forms to be left on longer is when it is a mass concrete section and heat differential is a problem. In this case the form may help in reducing the difference between the heat of the core of the concrete and the outer surface.

This "washed" away the cement and sand and left a real pretty aggregate finish. Often seen in lakeside settings - kind of fit in with nature?? Worked just fine.

You have to be very careful during the winter as the form removal process becomes more complicated, and maintaining the temperature of the concrete, while not "shocking" the concrete.
But I am sure someone on here will say that its not good practice to strip a footing or frost wall the next day in the summer...

I suppose we could specify a minimum amount of time the forms must stay on the walls. Does anyone here put anything definitive in their specs?

I never really see it in the specs but do see the aci references in the specs, aci 347 comes to mind but i am not sure.
