Question

How would I support a concrete slab roof on a 54' x 54' x 9'(height) with concrete blocks?

Answer 1

if you mean 54 ft. you will need to set bearing plates and bar joists...then use steel decking for your concrete base...

Answer 2

Well Farmer, do you really mean 54 feet X 54 feet?  If so, you've got way bigger issues than will be resolved here.  I can tell you though, nothing of that size and weight will be supported by concrete blocks with out a steel superstructure
