Abstract
The performance evaluation and the mix designing of self-compacting conrete should be approached on the basis of rheology in which fresh concrete is modeled as a Bingham plastic fluid with two parameters of yield value and plastic viscosity. In this paper, the constitutive equations explaining the flow of self-compacting concrete around a cyrindrical bar are induced by the application of Stokes' approximation to the Bingham plastic fluid. Theoretical discussion and experimental investigation using resin mortar led to not only proving the validity of the equations but also devising a method for quantitatively evaluating the behavior of self-compacting concrete flowing around a reinforcing bar from the rheological standpoint.
