For a conventional slab, 3 1/2". If you go 3 1/2" on a post tension slab (and some builders do...) the tops of the cables will be just below the top of the surface and surface cracks will form above the cables. I have even seen where the power screed will cut into the black cable cover.
The recommended thickness for a concrete slab is typically 4 inches for residential applications and 6 inches for commercial or heavy-duty use.
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.
The typical thickness of a slab foundation is around 4 to 6 inches.
The recommended thickness for a driveway concrete slab is typically 4 inches.
The recommended slab thickness for a house foundation is typically 4 inches to 6 inches.
The minimum covering of reinforcement for roof slab is 30mm
The recommended concrete slab thickness for a house foundation is typically 4 inches to 6 inches.
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.
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
The ideal thickness for a concrete slab when building a house is typically 4 inches to 6 inches. This thickness provides a strong and durable foundation for the structure.
