Filling hole in carport area

I recently removed a small flower bed that was surrounded on 3 sides by the carport slab and on one side by the house slab. My question is what process should I follow to fill this area with concrete. Most notably, I am getting conflicting info from the internet - some places say to use an expansion material next to the house, and some say to use / not use a bonding material.

Do I use an expansion material because I don't want a space to show between house slab and this slab because there is no space between the carport slab and the house slab?

Do I use bonding material? If so, only to the carport slab or to the house slab also?

Should I use reinforceing mesh even if it's only a 1 foot by 6 foot by 4 inches thick slab, or can I use fiber concrete products?


Thanks for any help!

 

To get it to look about the same as the surrounding concrete, do what they did originally. If there is expansion joint along the rest of the driveway, put it in. If not, then don't.
A 1 foot by 6 foot area is not going to cause major problems no matter what happens to it. Any bagged CONCRETE MIX (not mortar mix, not bagged fiber bonding cement) will work, whether it contains fiber or not. It would likewise be a waste of time to put wire in it. If you are nervous, put a single strand of #4 rebar in it and forget about it. Good luck.
