10n/mm2 is correct I think.

2/3 of local bond stress.

150 N/mm^2 (given).
i.e. 15 kg/cm^2,
= 2/3 * 15 = 10kg/cm^2.
i.e. 15 kg/cm^2,
= 2/3 * 15 = 10kg/cm^2.

150 kg/cm2 that means 15N/mm2. IS 456 -1978 given M15 grade of concrete design bond strength is 1 N/mm2 means of 10kg/cm2.

M150 means 150 n/mm2 so 15 kg/cm2 .
Then you can so 2/3 *15 = 10 kg/cm2.
Then you can so 2/3 *15 = 10 kg/cm2.

As per IS 456 Table 21 for WSM.
Permissible bond stress for M15 is 0.6 N/mm^2.
Permissible bond stress for M15 is 0.6 N/mm^2.

It is for M15 not M150.

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.

M10 1.0N/mm2 m20 1.2N/MM2 M25 1.4N/MM2 M30 1.5N/MM2 M35 1.7N/MM2 M40 and above 1.9N/MM2 and this is only for plain bar.
