Answer / maharshi

grades more than M25 should consists of mix designs so for
M30 grade mix design is necessary

Answer / tushar patel

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 / ramamurthy k l

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.

cment 390
20.00mm = 650
12.5mm = 450
river sand = 900
water =170

Answer / sandeep kumar

m30=1:1:1

Answer / soumya

Cement = 7.5 bags ( as per the cement content given 375
kg/m3)

sand content =0.45 m3
aggeregate =0.92 m3

Answer / ashalatha y

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

Answer / deven bhat

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.

In foundation design, while we do the base pressure check, we normally check if the attained pressure value is less than the GROSS BEARING CAPACITY of the soil which is the sum of net bearing capacity of soil and the overburden pressure. Actually, the overburden pressure acts against the net bearing capacity of the soil and I feel that we are actually increasing the bearing capacity value and doing the check. I feel that this is NOT right. Please clarify on this.
