ABSTRACT
The value: (N/sec), should be aimed at, where ds is the bar
diameter in mm.
The tension forces F found in the test are transformed by the following formula into bond stresses t dm and converted linearly to the medium value of the range of the concrete strength fcm
where fcm=30 or 25.5 N/mm 2 respectively and
fc=average of the tested specimens both according to 4.
