# Job Concrete Mix Volume

Written by Jerry Ratzlaff on . Posted in Civil Engineering

Job concrete mix volume, abbreviated as $$V_a$$, can determine the amount of concrete that needs to be delivered to a job site.

## Job Concrete Mix Volume formula

 $$\large{ V_a = \frac{ W_m }{ SG \; \rho_w } }$$

### Where:

$$\large{ V_a }$$ = absolute volume

$$\large{ \rho_w }$$   (Greek symbol rho) = density of water

$$\large{ SG }$$ = specific gravity of material

$$\large{ W_m }$$ = weight of material
