Dear Ben
Your point is not much clear. If you want reinforced brick concrete slab, than the procedure is as below.
Lay the miled steel bars @ 12'' center to center and place 3nos first class bricks jointed with cement mortar 1;4 in 12'' square than fill rest of the space with cement cocrete with top cover by 25 mm cement concrete after curing remove the shuttering and under side should be plastered.
