The frictional resistance of sandblasted interfaces due to aggregate interlock fails after a relative slip of 0.03 – 0.05 mm and is independent of the applied normal stress.

Design of slip-critical bolted connection assumes that the fastener, under high initial tensioning, develops frictional resistance between the connected parts, preventing slippage despite external load.
When a primary flexural crack forms and crosses the reinforcing steel, the concrete adjacent to the crack slips against the steel. Slip, or bond-slip, is defined as the relative movement […]
