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.
M 60 grade of concrete mixed peroration
Gsb is how the element of material is bond.

multiplying factor = Line CT Ratio / Meter CT Ratio Usually it is mentioned on Meter that MF = 1 if CT Ratio is 200/5 or MF = 2 if CT Ratio is 400/5. There can be an additional multiplication factor that would be mentioned on the meter.

The concrete truck is approximately 9' wide and 10'-12' high. The height of the truck can vary due to the size of the tires on the vehicle.
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?
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)
This information is probably somewhere on the bag.
Ration used in M10 concrete is 1:3:6 1 Cement, 3 Sand & 6 Aggregate
