18. It can be classified in different ways:
TYPE OF FLOOR SYSTEMS
It can be classified in different ways:
By Material Used
By Structural action of the slab
By Method of construction

19. By Material Used
Floor slab : Reinforced concrete, Timber, steel, brick
Beam or Girder : Reinforced concrete, Timber, steel

20. By Structural action of the slab
Bearing slab (Slab on ground)
One way slab
Two way slab
Joist slab, Waffle slab
Flat Slab
Irregular slab
