Thank you so much for all your replies. The concrete calculator estimates the volume and weight of concrete necessary to cover a given area. Length l width w thickness or height h quantity. Purchasing slightly more concrete than the estimated result can reduce the probability of having insufficient concrete.

For calculating self load for slab we have require self weight of concrete that is 2500 kg m3 for rcc slab and self weight of steel that is approx 8000 kg m3. A concrete roof is exactly what it sounds like. The weight of concrete is determined by its density which can vary based on the amount of aggregate water and air in the mix. A typical concrete mix weighs 150 lbs per cubic foot 4 050 lbs per cubic yard or 2 400 kg per cubic meter.

Then if it is p c c multiply it by 2400 as density of concrete is 2400kg cu m now for r c c u know the no. It is a form deck and not a composite slab. First we calculate weight of concrete in slab. Slabs square footings or walls.

Exact specifications vary but most concrete roofs are several inches thick. The building is old enough that the original specifications for the form deck is not available anymore although the profile is clearly visible from below at about 20 feet high and the concrete on top of the deck is 4 1 2 to 5 thick and reinforced with 4 bars at the bottom.
