The purpose of this paper is to evaluate experimentally the effect of hot dip galvanizing on the bond capacity of tension lap splices. Beam specimens were tested under 4-point loading with three parameters investigated: rebar size, lap splice length, coating.
Galvanizing is one of the methods used to solve the problem of corrosion of reinforcement in concrete structures. There are few research reported in the literature regarding the effect of galvanized coating on lap splices in concrete beams. The objective of this study was to determine whether galvanized rebar adversely affects lap splice behavior and bond strength.
Concrete beams reinforced with black or galvanized rebar were tested in flexure. The test variables included the presence of galvanized rebar, steel diameter and lengths of lap splices. The study concentrated on comparing crack pattern, failure pattern and bond strength. The ultimate behavior of beams reinforced with galvanized rebar was not significantly different from that of black steel reinforced beams.
The results from deflection and crack width measurements were indicative of no significant variation for the different rebar surface conditions. Therefore, the test results indicated that the use of galvanizing-coated rebar had no adverse effect on behavior in lap splices of rebar compared to the use of black rebar.
