BOND PROPERTIES OF HIGH FLUIDITY CONCRETE BEAMS WITH MEDIUM-QUALITY RECYCLED COARSE AGGREGATE AND MELT-SOLIDIFIED SLAG AGGREGATE
Abstract eng: For high fluidity concrete beams with medium-quality recycled coarse aggregate and melt-solidified slag aggregate, we investigated the fresh concrete properties and the bond splitting strength at the age of five weeks after placement. As a result, the flow value was approximately 60 cm without showing separation of materials, and favorable fresh concrete properties were achieved. The maximum flexural crack width under a long-term main reinforcement allowable stress was smaller for the high fluidity specimens (FRM type) than that of the non-high fluidity specimens (RM type). The bond splitting strength of the high fluidity specimens (FRM type) was generally higher than that of the non-high fluidity specimens (RM type).
