1:1:2 Hope it helps
proportion of M30 Grade of concreete is 1 :.5 :1 .
1:1:2 (1 cement: 1 sand: 2 coarse agregate)
The mix proportion for M40 concrete is 1:1.65:2.92W/C ratio = 0.4The design calculation is as per IS mix design
1:4:8
we use M30 grade concrete commercial slabs like shopping malls . college buildings
The standard mix is 123 That is one cement two sand three gravel
The weight of concrete can vary slightly depending on its composition, but generally, M30 grade concrete has a density of about 2,400 kg per cubic meter. Therefore, 1 cubic meter of M30 concrete weighs approximately 2.4 tons.

M30 concrete is commonly used in foundations due to its high compressive strength of 30 MPa, which provides adequate support for various structures. Its balanced mix of cement, aggregates, and water ensures durability and resistance to environmental factors. Additionally, M30 concrete offers good workability, making it easier to place and finish in foundation applications. This strength and reliability make it suitable for both residential and commercial construction projects.
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
M30 mix should be a mix design in laboratory with the available raw materials that is used in the preparation of concrete. The aggregates, sand have different compressive strength, water absorption and these values are used in mix design.
