Concrete Volume

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

 

Concrete Volume formulas

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