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

## Point Should Be Know Before Estimating

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 cement               = 28.8 Bags

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 for find Cement, Sand and Aggregate quality in 1 cubic meter concrete

• #### CALCULATION FOR CEMENT QUANTITY

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

• #### CALCULATION FOR SAND QUANTITY

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

• #### CALCULATION FOR AGGREGATE QUANTITY

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 m3 ∴ 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 find Cement, Sand  quality in mortar  for Plaster

Area of brick wall for plaster = 3m x 3m =9m2

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)

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

• Tutorial Tips Civil says:

every country have own IS code: this ration generally follow in India, I don’t know about other country you need your country IS code.
