The main purpose for using the blocks is to lighten the weight of the slap so that to decrease the dead load on the slab, in addition to save an amounts of concrete that wont give any added value to the slab.

 and yes, we can use strofoam instead as well.

These floors consisting of equally spaced ribs are usually supported directly by columns.

This form of construction is not very common because of the formwork costs and the low fire rating.
