List members:
I was recently asked a question on how soon a contractor can saw cut a 12 in concrete wall (boundary wall) to install crack control joints. The wall is free standing and varies from 5 to 10 feet in height. No expansion joints were planned. The rebar is in and concrete ready for pour.
Since a lot of the cracks are caused as the concrete dries and shrinks, it would seem appropriate to provide a saw cut as soon as possible. ACI requires concrete to be cured for at least one week (regular concrete).
I would appreciate your insight.
