Concrete slab calculator i.e Concrete slab cost calculator helps you to calculate the total cost of slab of required dimensions. This calculator provide flexibility to user to provide quantity of materials and unit rate of materials according to their area or state.

How to calculate concrete slab?

At first, convert all the dimensions of the slab ie. length, width, and thickness should be converted into a single unit.
After that multiply them and calculate the volume of concrete.
This is wet volume, we have to convert it into Dry volume. So, to do so, we have to add an extra 50% to 54% of wet concrete to get dry volume.

Numerical

Let us we have the dimension of slab, Length = 4 meter, width = 12 feet, Thickness = 4 inch. Calculate the concrete for slab of given dimension.

Solution,

Length = 4 meter

Width = 12 feet = 3.6576 meter

Thickness = 4 inch = 0.1016 meter

Now, Volume = Length x Width x Thickness

Volume = 4 x 3.6576 x 0.1016

Wet Volume = 1.4864 m³ (This is wet volume)

Dry volume = Wet volume x 1.54 = 1.4864 x 1.54 = 2.2891 m³

Hence, in this way we can calculate volume of concrete slab.

How much gravel under concrete slab calculator?

Now, in the above calculation, we have a dry volume of 2.2891 m³.

Now to get the volume of gravel or aggregate in slab, we need to choose the grade of concrete i.e ratio of cement, sand, and aggregate/gravel.

Let us choose, Cement : Sand : Aggregate = 1 : 2 : 4

Now, we have total coefficient of volume = 1+2+4 = 7

So, volume of gravel = (4/7) x Dry Volume = 1.302 m³

(4/7) is taken because we have 4 parts of aggregate in concrete.

Similarly, we can calculate the volume of sand and cement required in concrete.

How to calculate concrete slab cost?

After calculating dry volume of concrete, we have to calculate the volume of sand, volume of aggregate and weight of cement.

Now, multiply the volume of different materials with unit rate of materials per meter cube or per Kg.

For example we have, 3 m³ of Sand, 5 m³ of aggregate and 3 bags of cement and we have to calaculate concrete slab cost.

Let, The cost of aggregate be Rs.300 per meter cube, The cost of sand is Rs.200 per meter cube and Rs. 370 per bags of cement.

So, Total concrete slab cost will be,

Total Cost = Cost of aggregate + Cost of Sand + Cost of Cement

Total Cost = 3 x 300 + 5 x 200 + 3 x 370 = Rs. 3010
