As temperature changes stuff will either contract or expand. If the parts are big enough there's a risk that one end will be of a slightly different temperature than the other end. That'll have one end trying to change in size while the other end wants to remain unchanged. This leads to tension in the material which can cause it to crack. By casting the concrete in divided sections the risk for temperature-induced cracking is reduced.
The space between slabs is filled with tar (or some other flexible yet water resistant mass) to take up the expansion/contraction of the slabs.
no matter how big the concrete slab is, it will never float
Big sections can be made in one fill. Bricks need to be laid one at a time in rows by hand. You have to wait for the mortar to firm up before adding too much weight above. Concrete also can be made in sections off site & assembled on site
Usually concrete mix comes in 40, 60 or 80 pound bags.

Concrete floors are highly requested by people for industrial purpose as well as for home. They are durable, low cost and it requires very less maintanence. What I have done at my home is concrete flooring. I maintain it properly. A polished concrete floor just looks stunning. I recently polished the concrete floor in my home. I got it done from Floortex at Ontario, Canada. I should say a big thanks to the contractors because they have done such a good work. Polished concrete floors are resistant to moisture transmission issues too.

You can't get much more concrete than something that big.

Stone, brick, concrete and metal.
What size bags of concrete and how big are the bricks? Makes a difference.
