The answer will depend on the size of the concrete block!
Concrete, Mortar, Brick, Block, Re bar for support
Yes. Ron Lacher Pool Engineering in southern California probably has an engineering detail showing how to build it.
That's sort of a strange question. A concrete slab is a horizontal surface -- it's meant to be a surface you stand on or build things on. Concrete blocks are usually used for vertical surfaces -- walls. I believe that poured concrete walls are more expensive than concrete block walls. You wouldn't use concrete blocks as a substitute for a concrete slab.
They used concrete.
Use concrete to build a nice archway.
starting on the low ground side, dig a trench the full length and after pouring the concrete to almost ground level, start with your first block and as it heads into the trench, come back one half of a block and again pour the concrete to near ground level and lay another block and continue doing this until you reach the end. You will find that on your first course you will have only one block on one end and several on the other depending on how much out of level the ground may be. Hope this helps.
The volume of concrete used to build the Millau bridge is 85,000 m3 (cubic meters). The weight of this volume of concrete is 206,000 metric tons.

No one knows the exact amount of concrete used to build I-90. However, it did cost 1 billion dollars to build.

No, the Greeks were using bricks to build. It was the Romans that later on discovered the concrete.
