The ratio of cement, sand and crushed stone in M 25 grade concrete is 1:1:2.In this grade of concrete a compressive strength not less than 25 N/mm2 is achieved in 28 days.
between .15 and .20
as per ACI , the ratio between column & beam concrete grades dont exceed 1.4

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.

what is the concrete ratio in Class D2 concrete
What is mixing ratio for concrete grade 30
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.
cemet: sand: Agg=1:1:2 (Nominal Mix) Above answer is not as per engineering standards. For concrete mixing ration in M30 grade concrete, the mix has to be designed after testing all the materials including water in labs. When you go for higher grade of concretes the mix has to be designed , it is the water to cement ratio which has to be monitered for higher grades of concrete
