Concrete Floor Slab Thickness

It needs to be thicker if heavy equipment will rest on it.
Concrete floor slab thickness. Click the button to calculate the volume of concrete and man hours not including mixing needed for this job. Thickness of garage floor slab. 4 inches 0 1 m. 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.
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. The standards are expressed in terms of compressive strength which boils down to the amount of water used in the mix. The standard concrete garage floor is six inches thick and with use of proper control joints should be thick enough to withstand normal use. 5 6 inches 0 125 0 15 m porches home garage floors.
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. For slabs drying from two sides the depth is 20 of the thickness. 6 8 inches 0 15 0 2 m side walks barn and granny floors. This is largely based on the types and the number of vehicles you plan to park on it.
Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes. Structural concrete work is planned to bear loads or hold weight but transfer the weight to the soil base beneath the structure. Minimum thickness of concrete structural elements based on aci 318 14 irc 2009 is 456 2000 and ubc 1997 is presented. This calculator is to be used as an estimating tool only.
Design process includes proper assumption of structural element sizes and then check. Input length width and depth of the area. Steel reinforced slabs typically between 100 and 500 mm thick are most often used to construct floors and ceilings while thinner mud slabs may be used for exterior paving see below in many domestic and industrial buildings a thick concrete slab supported on. This test is called the relative humidity test using in situ probes and it s the basis for the astm f2170 standard.
For slabs drying from one side the depth is 40 of the thickness. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Building codes offer requirements for the concrete mix which vary by region. Common mistakes in concrete floor slab construction can be avoided with proper base preparation mix design placement finishing and curing.
For that reason knowing the thickness of the concrete slab is critical. Standard thickness of the garage floor slab used worldwide is 6 inches.
