# Concrete Volume

on . Posted in Civil Engineering Concrete volume, abbreviated as V, is a mixture of gravel, Portland cement, rock and sand.

## Concrete Volume formula

$$\large{ V = h \; l \; w }$$
Symbol English Metric
$$\large{ V }$$ = volume of concrete  $$\large{ft^3}$$ $$\large{m^3}$$
$$\large{ h }$$ = height of concrete $$\large{ft}$$ $$\large{m}$$
$$\large{ l }$$ = length of concrete $$\large{ft}$$ $$\large{m}$$
$$\large{ w }$$ = width of concrete $$\large{ft}$$ $$\large{m}$$

## Total Ratio of Cement Ingredients formula

$$\large{ T = r_c \;+\; r_s \;+\; r_{co} }$$
Symbol English Metric
$$\large{ T }$$ = total ratio of ingredients $$\large{dimensionless}$$
$$\large{ r_c }$$ = cement ratio $$\large{dimensionless}$$
$$\large{ r_{co} }$$ = coarse ratio $$\large{dimensionless}$$
$$\large{ r_s }$$ = sand ratio $$\large{dimensionless}$$

## Cement Guantity formula

$$\large{ Q_c = \frac{ r_c }{ T } \; V }$$
Symbol English Metric
$$\large{ Q_c }$$ = cement quantity $$\large{mol}$$ $$\large{mol}$$
$$\large{ r_c }$$ = cement ratio $$\large{dimensionless}$$
$$\large{ T }$$ = total ratio of ingredients $$\large{dimensionless}$$
$$\large{ V }$$ = volume of concrete  $$\large{ft^3}$$ $$\large{m^3}$$

## Coarse Gravel and Rock Quantity formula

$$\large{ Q_{co} = \frac{ r_{co} }{ T } \; V }$$
Symbol English Metric
$$\large{ Q_{co} }$$ = coarse quantity (gravel and rock) $$\large{dimensionless}$$
$$\large{ r_{co} }$$ = coarse ratio $$\large{dimensionless}$$
$$\large{ T }$$ = total ratio of ingredients $$\large{dimensionless}$$
$$\large{ V }$$ = volume of concrete  $$\large{ft^3}$$ $$\large{m^3}$$

## Cement Sand Quantity formula

$$\large{ Q_s = \frac{ r_s }{ T } \; V }$$
Symbol English Metric
$$\large{ Q_s }$$ = sand quantity $$\large{dimensionless}$$
$$\large{ r_s }$$ = sand ratio $$\large{dimensionless}$$
$$\large{ T }$$ = total ratio of ingredients $$\large{dimensionless}$$
$$\large{ V }$$ = volume of concrete  $$\large{ft^3}$$ $$\large{m^3}$$
