Self compacting concrete (SCC) is a breakthrough invention in the improvement of concrete technology. This material is distinguished by its special workability and the ability to compact itself, which is achieved without any mechanical vibration while the compressive strength and other properties are maintained more
than normal concrete performance. Fly ash and MIRHA utilization could raise awareness of environment safety and nature conservation due to effect of these discarded ash materials to air quality. SCC promises the superior performance whether in mechanical and durability properties and also widely known as very
high workability concrete in fresh condition. The other hand, the bonding strength characteristic of SCC is much or less understood, particularly SCC incorporating fly ash and MIRHA.. Pull out test was done to investigate the capability of bonding strength of fly ash SCC and MIRHA SCC. Fly ash SCC showed the
better performance compared to MIRHA SCC in maximum pull out force which is in line with bonding capacity, while the water binder ratio appears to govern the bond strength capacity. The increase in superplasticizers content reduces the anchorage bond stress, the bond strength values increased when larger steel bar diameter is used.   The effect of superplasticizers on bond strengthwas obtained in line with the compressive strength as the concrete with w/b of 0.4 with 4% SP dosage showed the maximum bond strength that was 40% higher than the bond strength of FASCC with 6% SP dosage. The increasing the water-binder ratio reduced the bond strength. FASCC with w/b of 0.4 yielded 70% lower bond strength as compared to that obtained in FASCc with w/b of 0.35.
