A Novel Self-Consolidating Concrete for Slip Form Application

In this paper, a novel concrete that can not only self-consolidate but also hold its shape right after casting is introduced. Such a concrete may have a great potential for slip form paving – providing more workable concrete, smoother and more durable pavement, and higher rates of production. In the consideration of the self-consolidating concrete for slip form paving application (SF SCC), the significances, version, and challenge of this innovative study are discussed. The research approach to the novel concrete through tailoring concrete materials and mixture proportions is described. The preliminary research activities, involving concrete flow ability, compactability, and shape-holding ability studies, are briefly presented. The results indicate that the newly developed SF SCC does possess sufficient self-consolidating ability and timely shape stability. The set time and strength of the SF SCC is comparable to those of conventional concrete. A lab simulation of the field slip form paving process has also demonstrated that such a SF SCC is feasible for field application.
