The minimum covering of reinforcement for roof slab is 30mm
1. one way slab 2. two way slab 3. flat slab 4. roof slab
Slab thickness is usually 7―" due to mechanical ducts located within the slab. This could be reduced to 6―" if the mechanical ducts are placed in a "bulk head".
7.5 inch
Dasign of T- beam is some what similar to rectangular beam, in design slab thickness is determined first. the slab is acts as compression flange in designing the beam. the flange acts as compression zone, which is balance by steel embeded in the bottom web of the beam. slab thickness= t, in. effective depth= d, in. width of web= b', in. flange width= b, in. width of flange should be least of the three alternatives, 1. span/4. 2. b' + 16t. 3. centre to centre spacing of beams.
Since most flat slabs contain reinforcing steel, the minimum would be the thickness required to cover the steel, generally 2" top and bottom. But the real answer depends on what the slab is supporting and the level of safety required. For a very general situation where the slab is supported on all sides and not significantly longer in one direction, a slab can be 6" wide and support light loading if properly reinforced.
A 22x22 foot slab at a 4-inch thickness/depth requires a minimum of 6 cubic yards.
The minimum area of steel required in RCC slab as per BS code is 0.12 to 0.15% of total area. The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.
You cannot. In general there is no relationship between the area of a slab and its thickness.
flat plates are solide concret slabs of uniform thickness that transfert load directly to the column without presence of projected beams and solid slabs surronding by beams
The different types of slabs are; one way slab, two way slab, flat plated slab, flat slab and grid slab
In flat slab you save time formwork of beams.
The minimum covering of reinforcement for roof slab is 30mm
I'll assume you are talking a slab 40' x 50'. if that is the case you would have to supply a thickness for an accurate answer. Also, whether or not you have chainwalls. With more information you can get a much closer answer. if it's a flat pour with 4" thickness the answer is appx 25 yards.
A large flat often thick piece of comething
slab gel with and without SDS
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
