AS per IS:456-2000,Concrete grade above M25 has to be
designed mix.for such higher grade W/C ratio,quality of
aggregates,admixtures are equaliy important parameters.So
M30 can never be designed in volumetric batching if
consistent quality control & strength is desired.
Mix Design There are two types 1) Nominal mix
Nominal mix based in volume nad experience
Design mix done using IS 10262 Code based on properties of
all ingredients ie sand aggregate water and cement finall
we are going arrive mix proportion in Wt.
