Minimum number of days beween pours at joints in RC base slab
Minimum number of days beween pours at joints in RC base slab
(OP)
Can anyone give me guidance or point me in the right direction on the minimum number of days between pours at contraction joints in a 12" RC base slab. The joints have a water-bar as it is in a tank. If the forms are pulled the day after pouring, to reduce shrinkage cracking the specification says seven(7)days must be allowed before casting against the joint. I have looked through ACI 302.1R, 304, 304.2R and cannot find any guidelines relating to this time frame.

Follow the specification. The time requirement is there for a reason...quality of the final project. I am sick of contractors going behind my back to the owner to complain about requirements which are for the owner's benefit.

Pay now, or pay later. This fix later will not be easy nor inexpensive.
