How To Calculate Cement, Sand, & Aggregate Quantity In 1 Cubic metre Concrete

cement sand aggregate quantity in 1 cubic meter

Point Should Be Know Before Estimating Concrete Quantity 

Density of Cement       = 1440 kg/m3
Sand Density                  = 1450-1500 kg/m3
Density of Aggregate   = 1450-1550 kg/m3

How many KG in 1 bag of cement                                 = 50 kg
Cement quantity  in litres in 1 bag of cement          = 34.7 litres
1 Bag of cement in  cubic metres                                  = 0.0347 cubic meter
How many CFT (Cubic Feet)                                            = 1.226 CFT
Numbers of Bags in 1 cubic metre of cement               = 28.8 Bags

The specific gravity of cement   = 3.15
Grade of cement                      =  33, 43, 53
Where 33, 43, 53 compressive strength of cement in N/mm2

M-20 = 1 : 1.5 : 3  = 5.5, (Cement : Sand : Aggregate)
Some of Mix is – 5.5

Where, M   = Mix
20  = Characteristic Compressive strength

Consider volume of concrete = 1m3

Dry  Volume of Concrete = 1 x 1.54 = 1.54 m3    (For Dry Volume Multiply By 1.54)

Now we start calculation to find Cement, Sand and Aggregate quality in 1 cubic meter of concrete


Cement in 1 cubic metre

Cement=  (1/5.5) x  1.54    = 0.28 m3   1 is a part of cement, 5.5 is sum of ratio
Density of Cement is 1440/m3

  = 0.28  x 1440 = 403.2 kg 

We know each bag of cement is 50 kg
For Numbers of Bags =   403.2/50     = 8 Bags 

 We Know in one bag of cement = 1.226 CFT

 For Calculate in CFT (Cubic Feet) = 8  x 1.225      = 9.8 Cubic Feet



Sand in 1 cubic metre

Consider volume of concrete = 1m3

Dry  Volume of Concrete = 1 x 1.54 = 1.54 m3

 Sand=  (1.5/5.5) x 1.54    = 0.42 m3   1.5 is a part of Sand, 5.5 is sum of ratio

Density of Sand is 1450/m3

For KG = 0.42 x 1450 = 609 kg

 As we know that 1m3 = 35.31 CFT

For Calculation in Cubic Feet   = 0.42 x 35.31 = 14.83 Cubic Feet



aggregate in 1 cubic metre

Consider volume of concrete = 1m3

Dry  Volume of Concrete = 1 x 1.54 = 1.54 m3

Aggregate =   (3/5.5) x 1.54 = 0.84 m∴ 3 is a part of cement, 5.5 is sum of ratio

Density of Aggregate is 1500/m 

Calculation for KG = 0.84 x 1500   = 1260 kg

As we know that 1 m3 = 35.31 CFT

Calculation for CFT  = 0.84 x 35.31 = 29.66 Cubic Feet

Now we start calculation for finding Cement, Sand  quality in mortar  for Plaster

Area of brick wall for plaster = 3m x 3m =9m2plaster quantity

Plaster Thickness = 12mm (Outer-20mm, Inner 12mm)

Volume of mortar = 9m2  0.012m            = 0.108m3
Ratio for Plaster Taken is                             = 1 : 6
Sum of ratio is                                                   = 7


Calculation for Cement Volume

Dry Volume of Mortar = 0.108  1.35 = 0.1458 m3

Cement= (1/7) = 0.0208 m3  

Density of Cement is 1440/m3

               = 0 1440              = 29.99 kg

               We know each bag of cement is 50 kg

               = (29.99/50)        = 0.599 Bags


Calculation for Sand Volume

Sand = (6/7) x 0.1458      = 0.124m3

Density of Sand is 1450/m3

               = 0 1450                = 181.2 kg

Now we find how many CFT (Cubic feet) Required

 As we know that 1m3 = 35.31 CFT

               = 0.124*35.31

               = 4.37 CFT (Cubic Feet)

    Can we multiply 1.54 cub meter in feet?

    • C P Singh says:

      First understand what is 1.54.
      1.54 is Multiplication factor to arrive at Dry Concrete qty from Wet concrete qty. ( Unit of qty can be in Cu. Ft or Cu mtr)
      A. For Example, Wet concrete qty for flat slab is Slab area x slab thickness * pl. Note all unit of measurement should be either in mtr ( to get wet concrete vol in cu. Mtr) or in feet (to get wet concrete Vol. In cu.feet)
      B. Multiply wet vol. By multiplication factor of 1.54 to get volume of Dry Concrete mixture. ** Total volume of concrete reduces by 1.54 times by adding water
      C. Unit of Volume of Dry concrete will be same as wet concrete.
      D. Divide Volume in cubic feet by 35.31 to get volume in Cu. Mtr.
      ** Same way multiply Volume in Cu. Mtr by 35.31 to get volume in Cu.ft.

  19. Abubakar Abdul Afeez says:

    Thank you very much for this invaluable breakdown. I have a question, I’m a Nigerian and the mix ratio we use some times get me confused. for example 1:3:6, and 1:2:4 are M15 and M25 respectively, I still see some people saying the latter is M20. Please, I want to really know what is the standard mix ratio. I would also love it if we can get most of your tips in pdf.

    Thank you

    A very concise and comprehensive tutorial.
    However I seek clarification. Does the multiplication factor (1.54) for dry concrete allow only for shrinkage in volume upon addition of water or does it also account for wastage?
