pier
I personally would recommend using steel reinforcing in the concrete. Is your pier adjustable at the top or is it levelled at the bottom? If it is adjustable I personally would weld threaded rod to the reinforcing steel in the pier itself.
I would also recommend NOT using quick set concrete, it is not structurally rated and it eats aluminium. Use standard concrete, its a lot easier to use and you will end up with a way better trowled finish, and is many times stronger.
