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.
