About the research

The objective of this research is to develop a new type of concrete that can self-consolidate (without vibration) and hold its shape right after slip-form paving. Different from the conventional self-consolidating concrete, which has very high flowability and requires formwork for construction, this new type of self-consolidating concrete for slip-form paving will have sufficient flowability (a slump of approximately eight inches) for self consolidation but be stiff enough to hold its shape right after paving, thus not requiring formwork for construction.
