Some useful construction tips on concrete mix design

This construction video tutorial focuses on concrete mix design. In this video grades are taken as M 7.5, M10, M15, M20 and mix ratios for cement, sand and aggregate are taken as 1:4:8, 1:3:6, 1:2:4, 1:1.5:3. The amount of water is required for amalgamating concrete in 50 kg cement.

Concrete mix design refers to the method of choosing the appropriate components (cement, sand and coarse aggregates) as well as their relevant proportions with the purpose of developing concrete by maintaining specific minimum strength & durability.
Objective of mix design
To make sure that the optimal ratios of the constituent materials is maintained to satisfy the need of the structure.
To obtain the preferred minimum strength in the hardened stage.

To obtain the needed minimum strength in the hardened stage.
To obtain the preferred strength in the specified environment conditions
To form concrete as inexpensively as possible.
