SHEAR TESTS ON VERY THIN EPOXY RESIN JOINTS BETWEEN PRECAST CONCRETE UNITS

摘要

Thirty-six short concrete beams, each consisting of three matched concrete blocks glued together, with thin films of an epoxy resin, were tested to determine whether the joints had adequate shear strength.nThe main variables were the method of preparing the contact surfaces, the method of applying the resin and the pressure (prestress) applied through the joints during setting and testing.nA simple method of applying pure shear to the joints was developed during the tests.
