Abstract
The report presents experiments that were run on adhesion of resin to rock, pull tests of resin anchored rebars, and bending tests of thinly laminated beams reinforced with resin bolts. The effects of hole diameter, bolt diameter, resin annulus, and hole conditions on anchorage, and the effect of bolt spacing on beam bending were determined.
