Weight Of Concrete For Roof Slab

A typical concrete mix weighs 150 lbs per cubic foot 4 050 lbs per cubic yard or 2 400 kg per cubic meter.

Weight of concrete for roof slab.

Of bars and their lengths. The concrete calculator estimates the volume and weight of concrete necessary to cover a given area. Firstly find the volume of concrete in cu m. It is a form deck and not a composite slab.

Length l width w thickness or height h quantity. A solid slab of concrete capping the top of your house. For example the florida based company hurricane proof systems offers a 7 inch 18 centimeter slab of concrete in three layers. Paroc air keeps the roof structure dry without any mechanical systems.

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. Self weight of slab is equal to weight of concrete in slab and weight of steel which is used in construction of slab. Learn more and see projects with hollowcore slabs. Thank you so much for all your replies.

Exact specifications vary but most concrete roofs are several inches thick. 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. Spancrete hollowcore precast concrete planks slabs are fire resistant reduce weight and costs. Hollow core concrete slabs paroc air is a simple and safe solution for making dry flat roofs.

Hole column or round footings. 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. 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.

First we calculate weight of concrete in slab. Researchers at the the technical school eth zurich have constructed a unique lightweight concrete ceiling by mixing computational design 3d printing and pre.
