Pull Out Tension Capacity of Self Compacting Concrete Containing Rice Husk Ash

Self-compacting concrete (SCC) is a relatively new kind of high performance concrete
product that sees the addition of superplasticiser and a stabilizer to the concrete mix to
significantly increase the ease and rate of flow. By its very nature, self-compacting
concrete (SCC) does not require vibration. It achieves compaction into every part of the
mould or formwork simply by means of its own weight without any segregation of the
coarse aggregate. For normal high strength concrete, bonding between concrete and rebar
can be considered relatively high due to vibration process. The study related to the shear
bond properties of self-compacting concrete and rebar. In additional, the self-compactingconcrete
added with admixture namely rice husk ash (RHA). Incidentally, this study
focused on the performance of self-compacting-concrete with rice husk ash (RHA) in
different three water-to-cement ratio for finding the optimum value of the ratio. Since this
study involves rebar and concrete, the performance measured with pull-out-test. The
pullout technique measures quantitatively the in-situ strength of the self-compacting
concrete when proper correlations have been made. At the end of this investigation, it is
identified the optimum water-to-cement ratio and super plasticizers in self-compacting
concrete (SCC) for maximum bonding stress between concrete and rebar. It is also to
identify the effect of rice husk ash (RHA) as filler in self-compacting concrete (SCC)
