Reinforcement to concrete bond strength: a comparison between normal concrete and various types of concrete

Abstract This paper describes the bond strength comparison between concrete and reinforcement with several types of concrete. The studied were normal (NC), Self-Compacting Concrete (SCC), High-Volume Fly Ash (HVFAC), (HVFA-SCC). Research data obtained from previous studies. by testing reinforced beam a lap splice in tensile moment area. Bond values normalized dividing square root grade. Then use to formulate relationship length diameter ratio (ls/db) for both SCC. From relationship, we can compare NC SCC is higher than NC. HFVAC HVFA-SCC also SCC, so that reduce need splice.
