Abstract: This invention relates to a reusable concrete form which is utilized to produce a concrete structure. The concrete form typically comprises a concrete form body portion, which is generally flexible in construction. The concrete form body portion is configurable during use to define a substantially circular or arcuate-shaped workspace. At least one fastener is attached to the concrete form body portion. In an assembled position, the fastener is interlockingly engaged so that the concrete form body portion defines a circular or arcuate-shaped workspace. In the disassembled position, the fastener is disengaged, and the concrete form is in a flattened configuration which is readily storable.
