Anotace

This test method deals with the standard procedures for establishing the relative bond strength of steel reinforcing bars in concrete using beam-end specimens. This test method shall determine the effects of surface preparation or condition (such as bar coatings) on the bond strength of deformed steel reinforcing bars to concrete. The bond strengths obtained using this test method shall not be directly applicable to the design of reinforced concrete members. The beam-end test specimen shall be fabricated by casting, and conditioned by curing prior to tensile load test. The test system shall consist of the loading system, compression reaction plate, and bar displacement measurement device.

Keywords:
