The development of self-compacting concrete (SCC) was a significant step towards effectiveness at
building sites, realistically producing prefabricated concrete rudiments, improved working conditions and better quality
and emergence of concrete structures. By addition of fibers to SCC, bar reinforcement can be replaced and the
performance of concrete structures improved. The variation of the bond strength along the flowing path for the different
mixes was evaluated. The steel-concrete bond adequacy was evaluated based on normalized bond strength. The results
showed that the bond strength was reduced due to Portland cement replacement with dolomite powder. The addition of
either silica fume or fly ash positively hindered further degradation as the dolomite powder content increased. The SCC
specimens were cast without applying compaction, whereas the specimens of normal concrete were cast by
conventional practice with substantial compaction and vibration. The results showed that SCC specimens generated
higher bond to reinforcing bars than normal concrete specimens and the correlation between bond strength and
compressive strength of NC is more consistent.
