To achieve m400 concrete, a special dosage of plasticizer chemical is added to a specific cement-aggregate-sand mix. This can only be done in controlled plant environment.

M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.
How to mix 4500 psi cement?
1:2:41 :2:3
Ration used in M10 concrete is 1:3:6 1 Cement, 3 Sand & 6 Aggregate
The mix proportion for M40 concrete is 1:1.65:2.92W/C ratio = 0.4The design calculation is as per IS mix design
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.

the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
1:2:41 :2:3
1:2:41 :2:3
The water/concrete ratio, not mixing it well enough, quality of raw materials, the age of the concrete, and the temperature and humidity of the area surrounding the concrete.
1:1.5:3:0.45 (cement,fine aggregate,coarse aggregate, water cement ratio)
There is no set ratio for a concrete requiring a compressive strength of m50. It is usually created according to the factors of the site condition and location.
This information is probably somewhere on the bag.
