Abstract:
A closure strip, otherwise known as a pour strip, is typically a temporary gap between two separate concrete slab placements. The closure strip is subsequently in-filled with concrete at a later date. Closure strips are common with staged construction where there is a construction sequence involved in casting the slab. Applications of closure strips can be found in bridge deck construction, post-tensioned slab construction, and normal two-way slab building construction. Requirements for strip width, shear transfer, and splices are discussed.
