What the difference between permissible and characteristics strength?
Raviraj Patel said:

It's 150 because M150 means M denotes design mix of concrete and 150 denotes the permissible comprehensive strength of concrete after 28 days of 150mm cube.
Like GRADE OF CONCRETE- CSO CONCRETE
M15 15
M20 20 Etc

Here, permissible strength is required to be determine fck 150 is already given. So, permissible strength= fck/partial safety factor.
150/1.5 = 100 kg/sq.cm.
fck = characteristic compressive strength of concrete at 28 days after curing.
150/1.5 = 100 kg/sq.cm.
fck = characteristic compressive strength of concrete at 28 days after curing.
