M20 1.2.
M25 1.4.
M30 1.5.
M35 1.7.
M40 1.9.

fy/Ym = 150/105 = 10.

The diff between the grade of concrete is 5 and design bond stress diff is 0.2 so for M15 grade the design bond stress is 1 N/mm2.

Means 10 kg/cm2.

For M40 and above bond stress = 1.9 N/mm2.

So D is correct.

There are only 15 grade of mix design of concrete from M15 to M85. So in above statement. the grade of concrete is M15.

Lakshmi said:   8 years ago
I think it is 10 N/mm2 because it is M15.

Chhaya said:   8 years ago
Yes, right @Sri.

B is correct as it is given in kg/cm2, if in N/mm2 then it is 1, also it M15 N/mm2 = M150kg/cm2.

B is correct as it is given in kg/cm2, if in N/mm2 then it is 1, also it M15 N/mm2 = M150kg/cm2.
Bond stress any concert is 2/3 of grade of concert.

2/3*15 =10 kg/cm2.
