CIP concrete over new brick connection
CIP concrete over new brick connection
(OP)
I have a condition where a 4 wythe brick smoke stack, aprox. 6'x6'x5' high, is to be capped with cast in place concrete ring and aluminum/SS cap. I am thinking about the connection of new brick and new concrete. I want to avoid drilling dowels into the new brick (as the arch currently shows on the attached detail). Are there any products available for a connection like this, I mean something that can be embedded within the joints to make the connection?
Thanks.
Thanks.

Brick tends to expand, while conc. tends to contract with time, so all-in-all keying them together may not be a real good idea. Maybe a case could be made for putting a through wall flashing on top of the brick, with a drip edge, and casting the cap on top of that flashing. Where is that cap going to go? Cast a retainer ring on the inside of the conc. cap. Put a 1x2 strippable form board against the brick on the inside of the chimney and cast the cap 2" lower than the top of the brick on the inside. Then, pull the form board, just a retaining ring is left.
You could also have some problems with that 4 wythe brick wall and moisture and heat on the inside and cold on the outer surface.
