this will be depend as per design mix.approx ratio will be available in is 4562000
Dear Sir, Mix Design is ok. Density of concrete is more than 2400kg/m3.i feel this canot be pumpable because 20mm quantity is too much. This is not econamical design.

if i use this job mix formulae for m20 grade concretethe strngth of cubes casted at rmc plant comes to 25 26 and 24 then
1.the mix may accepted at reduced rates
2 the mix may be rejected
3 the mix is as per is specification
