Mix Design Concrete Procedure - As Per Is Code | Grades of

Mix design concrete procedure has two objectives. One to achieve the minimum required strength and two to prepare the concrete in the most economical manner. Cost-wise, all concrete depends primarily on two factors, namely the cost of labor and the cost of material. Labor cost includes form-work, batching, mixing, trans porting, and curing, with slight variations between good bad quality concrete.

How to design different grades of concrete - Quora

I believe the different grades of concrete such 20mpa and 40mpa are created through the level of actual concrete powder added per mix. So therefore to create a stronger mix you may work on a 3 to 1 ratio and for a leaner mix perhaps a 5 to 1 mix.
