M 25
cement consumption in M-25
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.
What is mixing ratio for concrete grade 30
The Civil Engineering Data Standards manual states the density of many grades of concrete. Standard density for fresh M-25 concrete is: 2414 Kg/ M3.
The mix proportion for M40 concrete is 1:1.65:2.92W/C ratio = 0.4The design calculation is as per IS mix design

2503.4
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
For M25 grade concrete, the mix proportion is typically 1:1:2 (cement:sand:aggregate). This means for 1 cubic meter of concrete, you would need 1/4 cubic meter of cement. As 1 cubic meter is equivalent to 35.32 cubic feet, and one bag of cement usually covers around 0.035 cubic meters, you would need approximately 7-8 bags of cement for 1 cubic meter of M25 grade concrete.
M 15 grade proportion - 1:2:4 (cement:FA:CA)Cement required in kgs - 325 kg per cu.mNo. of bags required - 6.50
