Question

For batching $1:3:6$ concrete mix by volume, the ingredients required per bag of $50kg$ cement, are :

• A. $70$ liters of sand and $120$ liters of aggregates
• B. $70$ kg of sand and $140$ liters of aggregates
• C. $105$ liters of sand and $140$ liters of aggregates
• D. $105$ liters of sand and $210$ liters of aggregates

Answer 1

The correct option is D $105$ liters of sand and $210$ liters of aggregates

Volume of one beg cement $=0.035cum$.
Hence sand aggregates $=0.035\times 6=0.21cum$
$=0.035\times 3=0.105cum$
$1cum=1000Lt$
So sand $=\mathrm{0.1.5}\times 1000=105Lt$
and aggregates $=105\times 2=210Lt$
