Abstract: A good bond between old and new concrete is necessary for a successful repair of concrete structures.
The bond is usually determined through pure tension tests, e.
g.
, the common pull off test.
However, in most applications, the shear bond strength is more interested.
A test apparatus for torsion tests has been developed.
Laboratory and field tests have been carried out on cast in place concrete and shotcrete repairs.
For waterjetted surfaces, the obtained shear bond strength exceeds 3 MPa, i.
e.
, considerably more than the tensile bond strength which usually varies between 1 and 2 MPa.
The shear bond strength is also markedly higher than design strength values found in international codes.
