Concrete Floor Slab Thickness

Type of use how thick you pour your concrete floor can be determined by how the floor is going to be used.

Concrete floor slab thickness.

A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes. Standard thickness of the garage floor slab used worldwide is 6 inches. 6 8 inches 0 15 0 2 m side walks barn and granny floors.

The standard concrete garage floor is six inches thick and with use of proper control joints should be thick enough to withstand normal use. The thickness of concrete is an important factor in load bearing strength but to conserve resources and avoid over building other factors are also taken into consideration. Design process includes proper assumption of structural element sizes and then check. Input length width and depth of the area.

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. Click the button to calculate the volume of concrete and man hours not including mixing needed for this job. 4 inches 0 1 m.

This calculator is to be used as an estimating tool only. 4 5 inches 0 1 0 125 m farm building floors home basement floors. For that reason knowing the thickness of the concrete slab is critical. It needs to be thicker if heavy equipment will rest on it.

5 6 inches 0 125 0 15 m porches home garage floors. Quality floor construction includes good subgrade compaction even thickness slabs low slump concrete straight bulkhead lines and control cuts spaced 24 to 30 times the slab thickness. Structural concrete work is planned to bear loads or hold weight but transfer the weight to the soil base beneath the structure. For slabs drying from two sides the depth is 20 of the thickness.

This test is called the relative humidity test using in situ probes and it s the basis for the astm f2170 standard. The concrete slab should be four inches thick at least. Common mistakes in concrete floor slab construction can be avoided with proper base preparation mix design placement finishing and curing. Minimum thickness of concrete structural elements based on aci 318 14 irc 2009 is 456 2000 and ubc 1997 is presented.

The thickness of the garage floor slab depends on many factors such as types of loads coming upon the slab climatic condition design mix of the concrete and span of the concrete. Thickness of garage floor slab.
