Calculating the quantity of materials for the 100 sq.ft. of tile flooring.

Let us fix the tile of 2' × 2' size in the room of area 10 ft.× 10 ft. 

Let us use cement mortar of 1:4 ratio having 40 mm. thickness to fix these tiles.


  Calculation:

 1.  The number of tiles required

      = room area ÷ tile area

      = [(10ft × 10 ft.)÷  (2 ft. × 2 ft.)]

      = [100 sqft. ÷ 4 sqft.]

      = 25 nos.


The wet volume of cement mortar 

   = room area × mortar thickness

   = 100 sq. ft. × (40 × 0.00328084) ft.

       ( 1mm = 0.00328084 ft. )

   = 100 sqft.× 0.13123 ft.

   = 13.123 cu ft. 


Dry volume of cement mortar

   = 1.33 × wet mortar volume

   = 1.33 × 13.123 cu ft

   = 17.453 cu ft.

   = 0.4942 cum.

      ( 1cu ft = 0.0283168 cum. )


2. The volume of cement required

   = dry volume of floor mortar ×  (ratio of cement  ÷ total ratio)

   = 17.453 cu ft ×  ( 1 ÷ (1+4 ))

   = 17.453 × 0.2

   = 3.4906 cu ft.

   = 0.09884 cum.

     ( 1cuft = 0.0283168 cum. )


As you know, the density of cement = 1440kg/cum.

So, the total quantity of cement required in kgs.

   = 0.09884 cum. × 1440 kg/cum.

   = 142.3296 kg


One bag of cement weighs 50kg 

The number of cement bags required

  = 142.329 ÷ 50

  = 2.84 bags.


3. The volume of sand required

    = dry volume of floor mortar ×  (ratio of sand  ÷ total ratio)

    = 17.453 cu ft.×  ( 4 ÷ (1+4 ))

    =  17.453 cu ft.× 0.8

    = 13.9624 cu.ft.

    = 0.3953 cum.

   

        or

Volume of sand

    = volume of cement × 4

   = 0.09884 cum.× 4

  = 0.3953cum.

          or

Volume of sand

    = total dry volume- the volume of cement

    = 0.49421 cum - 0.09884 cum

    = 0.3953 cum.


Density of dry sand = 1602 kg/cum.

Weight of sand required

= 0.3953 cum × 1602 kg/cum

=   633.387 kg.

  1. I install laminate flooring in my new house & this flooring made my day easier. Because incredibly easy to keep clean. They can be swept, steam-cleaned, or vacuumed to remove any dirt or debris that has accumulated. However, JB Flooring helped me to install laminate flooring in my house. Laminate flooring Nashville
