WHAT IS SLAB?
 A slab is a broad, flat plate, horizontal with top and bottom surfaces parallel
or nearly so.
 It may be directly supported on beams or columns or indirectly on column by
using deep panel and column capital.
Types of Slab
Slab On
Beam
Flat Slab
Flat Plate
Slab
Waffle Slab
Construction Process of
Slab On Beam
1. Shuttering/Formwork
To form a desired shape of beam and
slab
Need to carry the weight of RCC of
slab and beam until hardening of
concrete
To resist falling of water from concrete until
hardening
2. Providing Steel Sheets
3. Maintaining Clear Cover
C.C blocks is used to maintain clear
cover
Clear Cover is needed to protect
the reinforcement from corrosion
4. Reinforcement Placing
The reinforcement are knotted with one
another using GI(Galvanized Iron) wire
The reinforcement are placed in two
direction
5. Concrete Casting
Casting was done monolithically where the
casting of beam and slab are done together
To reduce segregation, concrete was
dropped from low height
6. Compaction
The compaction is done by a
vibrator to remove air voids and
to make sure concrete has spread
uniformly in all direction.
7. Levelling
To Provide a smooth
surface
Levelling was done by
using a thick wooden
plate
8. Curing
The slab was ponded by water
for 28 days
To complete hydration
reaction in order to gain
strength of concrete
