ABSTRACT:
This invention is a paper-based concrete form member and a method for using it. The forms may be made from layers of paper honeycomb material or corrugate. The forms may be structured to be hollow, if so desired. They are principally useful in forming recesses or voids in concrete structures although they may be used to form the edges of concrete products during construction of these products.
