I think it is 150.

Agree @Bharath.

But what is the tensile compressive strenth of concrete?

Raviraj Patel said:   7 years ago
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.

What the difference between permissible and characteristics strength?

Pankaj said:   7 years ago
100 kg/cm2 is the right answer because we allow it after failure in compressive standard unit.
