Concrete Volume

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	\(\large{ft^3}\)	\(\large{m^3}\)
