5 = 72.5 pounds per cubic foot or 72.5 pounds per cubic meter. A 6-inch thick slab weighs 72.5 pounds per square foot, the maximum allowable weight. Do you know the weight of a 4-inch-thick slab of concrete? The weight per square foot is 47.85 pounds when divided by the number of decimal places in the formula (4/12).Do you need rebar for 3 inch slab?
Rebar is not necessary for every concrete project. The general rule of thumb is that if you are pouring concrete that is more than 5 inches in depth, you are probably going to want to add in some rebar to help reinforce the entire structure.Should I put wire mesh in concrete slab?
Concrete Wire Mesh Helps Minimize Concrete Slab Cracking and Settling. In fact, the best way to minimize the chance of cracking and settling is to use fiber mesh and WWM in the same slab. Like any structural product, WWM won't do its job unless it's installed correctly.Should concrete slab be bigger than shed?
If your shed doesn't have a floor, you should choose concrete. With a concrete foundation, your shed foundation should not be wider than your building; you will want to make it exactly the same size. As stated before, with a gravel pad, you will want to make your shed foundation 12″ wider than your shed on every side.Does a 4 inch slab need rebar?
No, rebar is not required for a 4-inch slab of concrete on grade. A 4-inch-thick slab cast on the ground and in constant touch with it will float, with no need for rebar. For concrete that is 5–6 inches thick, rebar is suggested.Do you need gravel under concrete?

Whilst not technically required, a subbase layer will provide your concrete shed base with a highly durable surface on which to sit, that won't collapse under the weight of your shed whilst also providing excellent drainage qualities. Once you add the subbase material, it will need to be compacted.How thick should a garage slab be?
The concrete slab should be four inches thick at least; it needs to be thicker if heavy equipment will rest on it. Building codes offer requirements for the concrete mix, which vary by region. The standards are expressed in terms of "compressive strength," which boils down to the amount of water used in the mix.How do I calculate how much concrete I need for a slab?
Let, Assume the slab has a thickness of 150 mm. Slab Load Calculation = 0.150 x 1 x 2400 = 360 kg which is equivalent to 3.53 kN. Now, If we consider the Floor Finishing load to be 1 kN per meter, superimposed live load to be 2 kN per meter, and Wind Load as per Is 875 Near about 2 kN per meter.What PSI should I use for concrete?
The ideal concrete psi for a given project depends on various factors, but the bare minimum for any project usually starts around 2,500 to 3,000 psi. Each concrete structure has a normally acceptable psi range. Concrete footings and slabs on grade typically require a concrete of 3,500 to 4,000 psi.What is the thinnest concrete can be poured?
