Abstract: In this paper, the development of a new concrete that can not only self-consolidate but also hold its shape right after casting is described. This concrete may have a great potential for slip form construction, such as slip form paving - providing a more workable mixture, eliminating internal vibration, increasing concrete production rate, and enhancing pavement smoothness and durability. The present study focuses on the test methods developed for evaluation of the concrete flow ability, compactibility, and shape-holding ability. The effects of materials and mix proportions on the concrete properties are also investigated. The results indicate that concrete materials and mixture proportions can be tailored to obtain sufficient self-consolidating ability and timely shape stability, thus suitable for slip form construction.
