Concrete Mix Ratio
The given concrete mix ratio is $1 : 1.5 : 3$. This represents the proportions of Cement : Fine Aggregate : Coarse Aggregate by volume.
Volume Batching Calculation
In volume batching, the volumes are measured directly according to the specified ratio.
- Total parts in the mix = $1 + 1.5 + 3 = 5.5$ parts.
- The proportion of coarse aggregate is 3 parts out of the total 5.5 parts.
- For a total concrete volume of $1.0 m^3$, the volume of coarse aggregate is calculated as:
$ \text{Volume of Coarse Aggregate} = \left( \frac{\text{Parts of Coarse Aggregate}}{\text{Total Parts}} \right) \times \text{Total Volume of Concrete} $
$ \text{Volume of Coarse Aggregate} = \left( \frac{3}{5.5} \right) \times 1.0 m^3 $
$ \text{Volume of Coarse Aggregate} = \frac{30}{55} m^3 = \frac{6}{11} m^3 $
$ \text{Volume of Coarse Aggregate} \approx 0.5454... m^3 $
Final Volume Determination
The calculated volume of coarse aggregate is approximately $0.545 m^3$. This value falls within the range specified in the answer.
