摘要：Electric arc furnace (EAF) slag is a by-product of steel production. Because the amount of slag produced is increasing each year, there is a growing need for effective methods of recycling this material. In this study, simple beam tests proposed by Ichinose were carried out to estimate the bond performance of reinforced concrete beams with EAF oxidizing slag aggregates. The main test variable was the type of aggregate used. A total of four specimens were designed to estimate the bond properties of top and bottom bars for the concrete. The bond test results revealed that the specimens with EAF oxidizing slag aggregates showed better bond performance than the basic specimen with natural aggregates. Furthermore, the experimentally observed bond strength of the specimens was compared with the theoretical results obtained from existing formulas. Consequently, the analytical results considering the effect of transverse reinforcement showed reasonable agreement with the experimental results.
