Presentation on Slab, Beam & Column
 Column is a vertical 
structural member 
 It transmits the 
load from 
ceiling/roof slab 
and beam, 
including its self-weight 
to the 
foundation.

 It is a flat 
horizontal 
surface 
 It is supported by 
beam and

Presentation on Slab, Beam & Column
 A rectangular 
column must 
have at least 4 
reinforcements 
at 4 corners
Circular column 
should have 
minimum 6 
reinforcements 
Reinforcement 
should be min 1% 
and max 8%
 It is done when 
length of 
reinforcement bar 
is small but we 
need longer 
reinforcement 
 Provided in mid 
span 
 Tied with hooks
 Columns have closed 
lateral ties spaced 
approximately 
uniformly across the 
column 
 Resist shear force 
and bursting out 
effect 
 10mm Ø, 12mm Ø 
bars are used
Normal 
spacing = S 
in mid span 
Spacing 
near support 
joint = S/2
Used to 
resist 
expansion 
The hooks 
shall be bent 
to 135º
Must be leak 
proof, smooth 
inside and 
properly aligned 
Should be 
maintained 1.5 
in clear cover
 Concrete is 
casted in two lifts 
 It should not be 
casted from more 
than 5 feet high 
to avoid concrete 
segregation
 Compaction is done by 
vibrator 
 Construction joints are 
provided for better 
bonding between new 
and old concrete 
 Formwork is removed 
after 3 days
Provides water 
for hydration 
reaction 
 Increases the 
strength up to 
2.5 times 
Done for 21 days 
Gunny bags are 
used for curing

STEEL FORMWORK WOODEN FORMWORK
A min. of 0.2% bar 
is to be provided 
for the 
compression in 
order to take care 
of the deflection 
 Extra tops are used 
in the support 
joints
Used to resist 
shear and 
diagonal tension 
stresses in a 
beam 
Shall be minimum 
size of 8mm ∅ in 
case of lateral 
load resistance
Alternate hook is 
provided 
The hooks shall 
be bent to 135º 
Stirrup 
distribution is 
dense near 
support
Casting and 
Curing are done 
simultaneously 
for beam and 
slab. 
Casting of lower 
part is done 
earlier
Side of 
formwork is 
removed after 
3 days 
Bottom part is 
removed after 
21-28 days

Extra tops near 
the supports
Mainly 1.5 " 
clear cover is 
maintained 
CC blocks are 
used
 Compaction is 
done with Patta
 Curing : It is done 
for 21 days 
 Removal of 
Formwork: After 
21 days formwork 
is removed
