Answer
# 2
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.

Answer
# 3
Mix Design There are two types 1) Nominal mix
2)Design Mix
Nominal mix based in volume nad experience
Proportion 1:1.5:3
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.

Answer
# 7
Proportion: 1:1:2

Quantity of Cement= 1440*0.92*2/4
=662.4 Kgs
=13.248 Bags
=13.5 or 14 Bags can be taken

1:1:2 is the logical mix design randomly used in mumbai &
costal part of india
cement consumption will be 500 kg for a M3 and water
requirement will be 300 ltrs for M3.
