Evaluation Of New Bonding Materials For Anchoring Dowels In Existing Concrete

Test results of threaded rod and reinforcing bars bonded with either polyester resin capsules, vinylester resin capsules, portland cement grout or magnesium phosphate concrete are presented. Tests included tension tests, shear tests, combined tension-shear tests, and creep tests at elevated temperatures. The parameters evaluated were edge distance, embedment depth, effect of elevated temperature on tension load, and the interaction of tension and shear. Tables listing allowable shear and tension loads have been prepared for each bonding material. An interaction equation for anchors loaded in both tension and shear is also given.
