Permissible tensile strength of concrete, M150.

RDJ said:   4 years ago
What is permissible TENSILE strength of M150 concrete?

Mohammad Al-Sous said:   6 years ago
kgf/cm^2 value = MPa value x 10.1972.

150Kg/cm^2 is the correct answer.

I think it is 150.

Agree @Bharath.

Shaban Kumar Mandal said:   4 years ago
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.

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/

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.
