# Concrete Volume

Written by Jerry Ratzlaff on . Posted in Civil Engineering

Concrete volume, abbreviated as V, is a mixture of gravel, Portland cement, rock and sand.

## Concrete Volume formulas

 $$\large{ V = h \; l \; w }$$ $$\large{ T = r_c \;+\; r_s \;+\; r_{co} }$$ $$\large{ Q_c = \frac{ r_c }{ T } \; V }$$ $$\large{ Q_s = \frac{ r_s }{ T } \; V }$$ $$\large{ Q_{co} = \frac{ r_{co} }{ T } \; V }$$

### Where:

 Units English Metric $$\large{ V }$$ = volume of concrete $$\large{ft^3}$$ $$\large{m^3}$$ $$\large{ Q_c }$$ = cement quantity $$\large{mol}$$ $$\large{mol}$$ $$\large{ r_c }$$ = cement ratio $$\large{ in^3 }$$ $$\large{ mm^3 }$$ $$\large{ Q_{co} }$$ = coarse quantity (gravel and rock) $$\large{ in^3 }$$ $$\large{ mm^3 }$$ $$\large{ r_{co} }$$ = coarse ratio $$\large{dimensionless}$$ $$\large{ h }$$ = height of concrete $$\large{ft}$$ $$\large{m}$$ $$\large{ l }$$ = length of concrete $$\large{ft}$$ $$\large{m}$$ $$\large{ w }$$ = width of concrete $$\large{ft}$$ $$\large{m}$$ $$\large{ Q_s }$$ = sand quantity $$\large{dimensionless}$$ $$\large{ r_s }$$ = sand ratio $$\large{dimensionless}$$ $$\large{ T }$$ = total ratio of ingredients $$\large{dimensionless}$$
