The proper way is to fill the column by using form work or box but in case you have difficulty than put concrete after raising brick work. In this case put 10% extra cement.

thanks for your swift response.
This one is in first floor and column have to be placed above 7 feet from the first floor level.
And also we have to raise only 2'6" But the available shutter (Box) height is around 4" ( i think).
Sir, if we put extra cement, will be there any strength issues ?
thanks | | |

The process of filling the column or
pillar with wooden planks after raising masonry..You should first fill the column with doing
proper form work and compact cement concrete by vibrator.
The process tell by you with wooden planks have following disadvantage
Disadvantages
- This is not water tight shuttering as the size and thickness of
planks differ and are not of same size. Due to this difference the water
and cement flow to the ground from joints and reduce the strength of
concrete.
- surface being uneven, the thickness of plaster is more which remains weak.
- Due to leakage of cement slurry through joints, earth work below ’'Ballies’ may settle and create problems.
- In some cases wooden planks can not bear the weight of concrete. Due
to low strength there is bending or deflection in wooden planks.
Sometimes the planks may break.
