Calculating the volume of cement required for a given quantity of concrete involves understanding the mix ratio and the volume of concrete to be prepared. In this case, we are given a mix ratio of 1:2:4, which means that for every unit of cement, we need 2 units of sand and 4 units of aggregate.
To find the volume of cement required, we can use the following equation:
Volume of cement = (1/7) x Total volume of concrete
Where 1/7 is the proportion of cement in the mix ratio (1+2+4=7).
Given:
Total volume of concrete = 150 Cu-m
Calculation:
Volume of cement = (1/7) x 150 Cu-m
= 21.43 Cu-m
Rounding off to the nearest whole number, we get:
Volume of cement = 21 Cu-m
Therefore, the estimated volume of cement required to prepare 150 Cu-m of 1:2:4 concrete is 21 Cu-m.
Summary:
To calculate the volume of cement required for a given quantity of concrete, we use the equation Volume of cement = (1/7) x Total volume of concrete. In this case, the total volume of concrete is 150 Cu-m, so the volume of cement required is 21 Cu-m.

1:2:4 concrete mix denotes, 1 part of cement, 2 parts of sand, and 4 parts of coarse aggregate in that particular concrete mix.
1 m3 freshly mixed concrete corresponds to 1.54 m3 dry volume of concrete.
Calculation:
Given,
Wet volume of concrete = 150 Cum, Concrete mix = 1:2:4
1 m3 freshly mixed concrete corresponds to 1.54 m3 dry volume of concrete.
150 m3 freshly mixed concrete corresponds = 150 × 1.54 = 231 m3 dry volume of concrete
In a concrete mix of 1:2:4, Total parts = (1 + 2 + 4) = 7
In a total of 7 parts, cement volume is 1 part, i.e. 1/7
Hence, Cement volume for 231 m3 dry concrete = (1/7) × 231 = 33 m3
1 m3 freshly mixed concrete corresponds to 1.54 m3 dry volume of concrete.
Calculation:
Given,
Wet volume of concrete = 150 Cum, Concrete mix = 1:2:4
1 m3 freshly mixed concrete corresponds to 1.54 m3 dry volume of concrete.
150 m3 freshly mixed concrete corresponds = 150 × 1.54 = 231 m3 dry volume of concrete
In a concrete mix of 1:2:4, Total parts = (1 + 2 + 4) = 7
In a total of 7 parts, cement volume is 1 part, i.e. 1/7
Hence, Cement volume for 231 m3 dry concrete = (1/7) × 231 = 33 m3
