Not for M150, grade 15, but this is nominal mix design not for mix design.

Ld=dia* σ st/4 permissible bond stress.
Ld=130*dia/4*.6=58dia.

For
M15 58d
M20 47d
M25 40d
M30 38d In tension.

Tbd = 6kg/cm^2= .6 n/mm^2.
Ld= (.87x250xd)/(4x1.25x.6)= 58d.

No, length of embedment differs with the diameter of rebar.

How to calculate 58d?

Please give the correct explanation.

Does length of embedment differs with grade of concrete?

Argha said:   10 years ago
I think the grade of concrete should be M15 not M150.
