    How many tonnes can you put on a concrete floor that’s only two inches thick?

    The pressure exerted on a 2-inch thick concrete slab is 750 psi. For the best possible durability, slabs are often reinforced with concrete that is at least 2 inches thick. The typical slab thickness is four inches.
    It is common practise to pour concrete to a depth of 2 inches or more so that the resulting slab will be as robust as possible. The typical thickness of a slab is 4 inches. This is the ideal thickness for a slab, at four inches. Effective concrete slabs typically range from 2 to 4 inches in thickness. It is recommended, however, that the slab’s perimeter be thickened by an inch or two.

    How many tonnes can you put on a concrete floor that’s 6 inches thick?

    A compression force of 1,105 psi is not enough to crack a 6-inch thick slab of 700 psi concrete. It could withstand 1,194 psi at a thickness of 7 inches and 1,563 psi at a thickness of 12 inches. In comparison to its compressive strength, concrete’s tensile strength is only about 10% to 15% as high. An appropriately compacted and levelled 6″ thick concrete slab has a compressive strength of 3000 to 4000 psi and a tensile strength of 300 to 600 psi.

    What is the maximum load capacity of a concrete slab?

     A concrete slab that is at least four inches thick can withstand loads of up to 3,000 pounds per square inch (PSI) in compressive strength. On certain 4-inch slabs, the maximum load bearing pressure is 40 lbs. Even though 80 lb/sq ft is fine in some spots, the slab as a whole could crack if the soil bearing and reinforcing conditions are not known.

    To what extent can concrete support weight?

    The maximum load that may be supported by concrete is proportional to its thickness. Structural concrete is made to transfer the load of a structure to the ground below.

    Even though the thickness of the concrete is a big part of how much weight it can hold, other factors are also taken into account to make sure it works well and avoid building things that don’t need to be built.

    Depending on what the building is going to be used for, there are minimum thickness requirements for the concrete, and the material is often made thicker than those requirements. 


    The loads and dimensions of the slab determine the thickness of the concrete. A slab thickness of 6 inches (150 millimetres) is typically used for both residential and commercial construction, with reinforcement features as per design. Slab thickness can be determined in a number of ways, depending on the material.
