Hello and thanks to all in advance!
I am building a double gate to store my travel trailer and ran out of concrete. I mixed what I had and poured it into the hole and I still have about 4 to six inches to cover! On one post I used the fast curing quickcrete and the other post a 24 hour curing time. My question would be, could I just add a new batch of concrete on top of what I have ready started? Also, it started to rain roughly 3-4 hours after a mixed the concrete, should I be concerned about the bonding? The rain is not as bad as other places as I reside in southern California. Thank you!

Yes to your question,and if your worried about bonding,just use a bonding agent before you do the final batch.

Yes and don't waste the money buying bonding agent. Do moisten the old before the new pour.

altho if it were our job, we wouldn't use a bonding agent,,, you have a conc base for the post - now all you're doing is pouring a collar which will move from frost but not enough, imo, to justify bonding agent even tho, technically, woody's right

( wow, that tasted like vinegar coming out of my mouth ! )

Do you really think frost will move it where he's located??
