Today I will tell, how PCC pole concreting is done? Before knowing about our topic, let's take a little knowledge about PCC Polls.full form of pcc pole is Plain Cement Concrete pole.There are various types of PCC Pole like 8 mtr 8.5 mtr ,9 mtr .but Now I will discuss about only 8.5 mtr pcc pole.
As per Guaranteed Technical Perticulars(GTP)
- Total Length-8.5 mtr
- Pit depth-1.5 mtr
- Working load applied 300 mm from top-180 kg
- Weight of the pole-415 Kg.
- Top dimension-90mmx145 mm
- Bottom dimensions-90mm x 300 mm
we have to maintain pit length is 1.5 mtr and pole should be inside pit is L/6 where L is length of the pole.
Explained:
L=8.5 mtr
Pit depth=L/6+0.075(Base plate)
Pit diameter =20 inch(0.508 mtr)
Let's go to our topic now.
How to calculate cement, sand and aggregate quantities for ratio 1:2:4
Pit Size |
- For one cmt cement required -6 bag
- Our pit volume (dia-0.508 mtr where r-0.254, depth-1.5 mtr)
- Volume -pie*r2*h
- For one cmt, bag of cement required -6 bag
- and our pit volume is 0.304cmt
- Pole and base plate in volume inside pit is 0.3x0.09x1.5=0.04
So we get 0.264 cmt.If for one cmt,bag of cement require is 6 bag then for 0.264 cmt
as below.
Cement =0.264x6=1.5 bag cement.
Sand=3 bag (bag is Cement bag size)
Aggregate=6 bag(bag is Cement bag Size)
