Abstract: The use of self-consolidating concrete (SCC) is necessary for improving the constructability of concrete: congested reinforcement makes vibrated consolidation difficult and quick placement is beneficial for speeding up construction. Oftentimes called flowable concrete, the most important quality of SCC is flowability but shape stability is desired for field applications, as well. Conventional SCC with low shape stability results in high horizontal formwork pressure. Adjusting the shape stability of SCC can also produce semi-flowable concrete for slip form construction, which should be capable of consolidating under its own weight during casting but hold its shape immediately after placement. These applications call for the need to balance flowability and shape stability. We need to balance flowability and shape stability when occasion demands.
