volume 12Concrete 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 \(\large{dimensionless}\)
