What type of concrete mix should I use, to teem surrounded by cracks surrounded by my driveway?
Answers: a pod of sand mix concrete should work nicely , for a while.
That is a mix of 3 sand to one cement , mix it to a somewhat dry consistancy , but it should cling together on a trowel, not drippy.
Fill the crack after wet the concrete to help it stick.
It may shrink a short time , but keep it showery for a few days to help it cure.
There are various concrete patch mixes that may work better , try your local building center.
Use non-shrink grout. You can get it from your local lumber patio.
They make a vinyl concrete patcher for basically what you describe. They have it at Lowes or Home depot.
Check the quickrete trellis site see what they say....
