Abstract
This paper explains the bond strength between the reinforcing bar and High Volume Fly Ash-Self Compacting Concrete (HVFA-SCC). The bond strength is determined by a pull-out test on the concrete cube (200x200x200 mm) with a single steel bar centrally placed in the cube following the RILEM standard. The HVFA-SCC is proportioned with an inclusion of 50% fly ash by weight of the total binder. The concrete satisfies the flowability criteria of SCC and has the average concrete compressive strength of 38.8 MPa. The test result shows that an average bond strength of HVFA-SCC is 12.93 Mpa and 3.89 MPa for deformed and plain bars, respectively. The obtained bond strength of HVFA-SCC is compared with the bond strength of other concrete types found in the literature. It confirms that the HVFA-SCC bond strength is higher than normal concrete (NC), and comparable with geopolymer concrete (GC), HVFAC, and SCC.
