The mixes of grades M5 M10, M15, M20 and M25 correspond approximately to the mix proportions (1:4:8), (1:3:6), (1:2:4), (1:1.5:3) and (1:1:2) respectively.

The main difference between concrete grade C35 and C35A lies in their composition. C35 concrete is a standard concrete mix with a minimum strength of 35 megapascals (MPa), while C35A concrete is a special mix that includes air-entraining agents to improve workability and durability. The inclusion of air-entraining agents in C35A helps to increase the concrete's resistance to freeze-thaw cycles and reduce the risk of cracking. Overall, C35A is more suitable for applications where improved durability and workability are required.
