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.
Means 10 kg/cm2.

For M40 and above bond stress = 1.9 N/mm2.
So D is correct.
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.

I think it is 10 N/mm2 because it is M15.

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.
Bond stress any concert is 2/3 of grade of concert.
2/3*15 =10 kg/cm2.
