Hi everyone, I have a question regarding construction joints in concrete. I am working on a parking garage (256'x120') that has a 3.5" concrete topping slab supported by precast double T's. The contractor will pour the middle 1/3 of the topping slab first, then pour the two ends after that. My question is, how long should he wait to pour the ends after pouring the middle section? Are there any recommended standards by ACI for this issue? Any help would be appreciated.
