Process for calculating the quantity of cement, sand and aggregate in a concrete slab

This is another useful construction video tutorial presented by Sami Ullah Stanikzai, the renowned engineer. In this video, Sami shows in detail how to estimate the quantity of cement, sand and aggregate for a concrete slab.

The length and width of the slab is taken as 14 feet. There is also a cross section. The length of this cross section is also taken as 14 feet and the depth of this cross section is 6” i.e. 0.5 feet.

A concrete slab is recognized as a common structural element of modern buildings. The density of horizontal slabs of steel reinforced concrete generally lies among 4 and 20 inches (100 and 500 millimeters). These frequently utilized to build up floors and ceilings, whereas thinner slabs are also applied for exterior paving.

Often these thinner slabs contain the density between 2 inches (51 mm) to 6 inches (150 mm) whih are known as mud slabs. These are mainly utilized under the main floor slabs or in crawl spaces.

To develop the ground floor of a building in various domestic and industrial buildings, a dense concrete slab is supported on foundations or directly on the subsoil . These can range from "ground-bearing" or "suspended" slabs. In high rise buildings and skyscrapers, slimmer, pre-cast concrete slabs are driven among the steel frames to build up the floors and ceilings on each level.

On the technical drawings, reinforced concrete slabs are demonstrated as "r.c.c.slab" or simply "r.c." in short form.

Watch the following video to get the complete process.
