To calculate the water to cement ratio:
\[ W:C = \frac{\text{WV} \times 1680.5}{\text{CW}} \]
Where:
The water to cement ratio is defined as the total ratio of the weight of water to the weight of cement used in a cement mix.
Let's assume the following values:
Using the formula:
\[ W:C = \frac{2 \times 1680.5}{500} = 6.722 \]
The Water to Cement Ratio is 6.722.
Let's assume the following values:
Using the formula:
\[ W:C = \frac{1.5 \times 1680.5}{400} = 6.301875 \]
The Water to Cement Ratio is 6.3019.
