Resources on Self-Consolidating Concrete--Applications for Slip-Form Paving

The overall objective of this project is to develop a new type of self-consolidating concrete (SCC) for slip-form paving to produce more workable concrete and smoother pavements, better consolidation of the plastic concrete, and higher rates of production.

Phase 1 demonstrated the feasibility of designing a new type of SF SCC that can not only self-consolidate, but also have sufficient green strength.

Phase 2 will focus on developing a SF SCC mix design in the lab and a performing a trial of the SF SCC in the field. Phase 3 will include field study, performance monitoring, and technology transfer.
