Rebar bars bonded to masonry structure
Rebar bars bonded to masonry structure
(OP)
HILTI produces a chemical grout (e.g. HIT-HY 150) which is able to bond the new steel bars to the existing concrete. However, this product is applicable to concrete structure, does any body there is manufacture has a similar chemical grout for masonry structure?

What kind of a masonry structure (type of units, type of construction, strength of units and grout?)
HILTI should be able to provide some technical support that you could apply to existing engineered masonry standards, research and general information.
A correct assumption would be that any grout in the masonry is the same strength as the masonry units, but some mis-informed person may have specified a high strength grout.

Otherwise you're guessing (not good). Do not use concrete test values with masonry. Masonry is not as strong as cast-in-place concrete where anchors are concerned.

HY 20 seems not to strong enough.........Any alternative??

Each metre strip of the abutment is required to reist a 120 KNm BM (not factored yet)...
