The standard mix is 123 That is one cement two sand three gravel
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
Concrete mix is made from (sharp)sand, cement, aggregate and water. The ratios depent on the usage
Concrete :- a mix of cement, sand, water, and gravel. Mortar :- a mix of cement, sand, and water
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.

The proportion of the bed mortar should be 4:1 for the sand : cement.

The property of concrete which determines the amount of useful work (like- water content, mix proportion, size of aggregate used and use of admixtures) necessary to produce full compaction is called workability.
Lean mix concrete is used for substructures like foundations,piles,etc.,Ready mix concrete is used for superstructures and also for mass construction.Generally, quality of ready mix concrete is good when compared to the lean mix concrete.Workability of lean mix concrete is high when compared to RMC.
