Commercial Site Visit: Form Removal

         This afternoon; Friday 12/3/10; I returned to the dining hall construction site to see if the forms had been removed from the curing concrete and sure enough they had been and a new set of forms had been constructed. The concrete had been poured into the last forms on Wednesday, 11/1/10.  The concrete was given 48 hours to cure before the forms were removed.  As these forms were removed, a new set of forms were erected in order to start a new segment of the wall.

This is a photo taken before the forms were removed.

Here is a photo after the forms had been removed.  As you can see plywood

has been used to brace the corner of the walls to provide support as the new forms

are put up and the weight of the concrete is added to the new forms.

          It is important to brace the corner of the wall because as the weight of the concrete is added to the right wall, the pressure will increase on the left wall.  Because the fresh concrete is still curing it is not at full strength, and the added pressure could cause a failure.

           I also have noticed that there is a darker color to the fresh concrete which could be because it is not fully cure and the water is still evaporating out to the surface.

          Once again as you can see, a tarp has been draped over the top of the plywood forms to protect them from any rain which could delay a concrete pour.
