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 density of cement in a grade 25 concrete mix typically ranges from 1440 to 1600 kg/m³. However, the overall density of the concrete mix, which includes aggregates and water, is usually around 2400 kg/m³. The specific density can vary based on the materials used in the mix and their proportions.
M-25 grade concrete refers to a specific mix of concrete that has a characteristic compressive strength of 25 megapascals (MPa) or approximately 3625 psi when tested at 28 days. The "M" stands for "mix," and the number indicates the strength of the concrete, which is achieved through a specific ratio of cement, sand, aggregate, and water. Typically, M-25 is used in structural applications such as beams, columns, and slabs where higher strength is required. This grade is commonly used in medium-strength construction projects.
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
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.
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 .
