(countable) A moveable form used when setting concrete using the slipform technique.Examples: "Slipforms of various designs have been used with excellent results."; "The slipform is fed with concrete from a crane-carried or rail-mounted bucket."; "Vibration may be used ahead of the slipform, but consolidation must be completed as the concrete passes under the form."countable
