I'm making a 9' x 8' x 3" slab as part of a repair to my driveway. The old driveway concrete has been removed from this space. The new concrete will abut the original driveway on both sides. I'm planning on dividing it into two 4.5' x 8' sections and pouring them separately.
The two concerns I have are:
The largest mixer at my rental place can mix 10 80lb bags and each section will take about 18 bags. Should I further divide the section to do 9 bags at a pour or is it OK to pour two batches one right after/on top of the other.
Do I wait until the first section is cured or partly cured before pouring the adjacent section? There will be an expansion joint spacer between them.
