Cement, Sand and Aggregate Quantity in Concrete

Here I have consider Concrete Volume (WET) = 1 Cubic Meter

Grade of Concrete Mix = M15 (Cement = 1 : Sand = 2 : Aggregate = 4)

Sum of the ratio of Cement, Sand & Aggregate = 1+2+4 = 7

First we have to find the Dry Volume of Concrete by Increasing the Wet Volume by 54 percent.

Dry Volume = Wet Volume x (54% of Wet Volume)

= 1 x (54 x 1 / 100) = 1.54 Cubic Meter

Now we have to find the quantity of Cement, Sand & Aggregate. Here I will show you the calculation of quantity in different units like Cubic Meter, KG, Bags, Cubic Feet.

CEMENT

1) Cubic Meter = Dry Volume x (Ratio of Cement / Sum of Total Ratio)

= 1.54 x (1 / 7) = 0.22 Cubic Meter

2) KG = Dry Volume x (Ratio of Cement / Sum of Total Ratio) x Density of Cement

= 1.54 x (1 / 7) x 1440 = 316.8 KG

3) Bags = We know, 50 KG = 1 Bag of Cement

316.8 KG = 316.8 / 50 = 6.336 Bags of Cement

4) Cubic Feet = If we multiply Number of Cement bags by 1.226, we get the value in Cubic Feet i.e. 6.336 x 1.226 = 7.77 Cubic Feet

SAND

1) Cubic Meter = Dry Volume x (Ratio of Sand / Sum of Total Ratio)

= 1.54 x (2 / 7) = 0.44 Cubic Meter

2) KG = Dry Volume x (Ratio of Sand / Sum of Total Ratio) x Density of Sand

= 1.54 x (2 / 7) x 1450 = 638 KG

[Density of Sand varies between 1450 – 1500 KG per Cubic Meter]

3) Cubic Feet = Dry Volume x (Ratio of Sand / Sum of Total Ratio) x 35.3147

= 1.54 x (2 / 7) x 35.3147 = 15.54 Cubic Feet

[NOTE : 1 Cubic Meter = 35.3147 Cubic Feet]

ALTERNATIVE : No. of Cement Bags x Value of one bag of cement in Cubic Feet x Ratio of Sand

= 6.336 x 1.226 x 2 = 15.54 Cubic Feet

AGGREGATE

1) Cubic Meter = Dry Volume x (Ratio of Aggregate / Sum of Total Ratio)

= 1.54 x (4 / 7) = 0.88 Cubic Meter

2) KG = Dry Volume x (Ratio of Aggregate / Sum of Total Ratio) x Density of Aggregate

= 1.54 x (4 / 7) x 1500 = 1320 KG

[Density of Aggregate varies between 1450 – 1550 KG per Cubic Meter]

3) Cubic Feet = Dry Volume x (Ratio of Aggregate / Sum of Total Ratio) x 35.3147

= 1.54 x (4 / 7) x 35.3147 = 31.07 Cubic Feet

[NOTE : 1 Cubic Meter = 35.3147 Cubic Feet]

ALTERNATIVE : No. of Cement Bags x Value of one bag of cement in Cubic Feet x Ratio of Aggregate

= 6.336 x 1.226 x 4 = 31.07 Cubic Feet
