Question

How to calculate cement sand and aggregate quantity in m20 concrete?

Answer 1

Answer:M20 1:1.5:3 where 1 is cement, 1.5 is sand nd 3 is aggregate.

For Dry mix: take 1 m^3 concrete

{1/(1+1.5+3)}*1(cement)=0.1818m^3 cement.

No. Of bags :

0.1818/0.034722=5.2approax 6 bags.

Now for sand

{1/(1+1.5+3)}*1.5=0.272m^3

Now for aggregate

{1/(1+1.5+3)}*3=0.545m^3.

Same for wet concrete but only change we take 1.54m^3.
