An apparatus for use in concrete construction is characterized by a body having a first portion configured to be set into concrete during the casting of that concrete, and which can be removed from the concrete after the concrete has set, and thereby may be reused in a similar manner with other concrete castings. The body of the apparatus is preferably generally cylindrical and preferably includes a serrated exterior surface. The body also preferably includes a second portion configured to facilitate removal of the apparatus from the concrete, and further includes an engagement member with which other devices may be engaged. The second portion may also be engageable with an alignment member to facilitate the accuracy of insertion and removal of the apparatus from the concrete. The serrated exterior preferably interferingly engages with at least one reinforcing element formed in the concrete, to assist in positioning of the concrete. The body may also be inflatable, and thus removable from the concrete by deflating. Inflatable and non-inflatable embodiments of the apparatus find use in "no-slump" or extrusion concrete applications. A preferred method of use of the apparatus is disclosed.

DETAILED DESCRIPTION I claim: 1.
A method of creating void space in concrete material, including the steps of: (a) providing concrete material; (b) providing a form for casting said concrete material; (c) providing a removable, reusable insert member, said insert member is attachable to machinery capable of providing a continuous supply of relatively rapid setting concrete, and said method includes the step of attaching said insert member to said machinery; (d) positioning said insert in a selected position with respect to said form, to facilitate said removal and reuse of said insert member; (e) casting said concrete material in said form and around said insert member; (f) removing said insert member from said concrete material after said casting, said removal step consists of rotably removing said insert member from said concrete material; (g) providing at least one reinforcing element; and (h) positioning said at least one reinforcing element in said form between adjacent serrations on said exterior surface of said insert member.
2.
The method of claim 1, in which said insert member includes a generally cylindrical body having a serrated exterior surface.
3.
The method of claim 1, in which said insert member includes a generally cylindrical body having a serrated exterior surface.
4.
The method of claim 1, in which said insert member includes a generally cylindrical body having a serrated exterior surface.
5.
The method of claim 1, wherein the insert member has a first portion and a second portion and wherein the method further comprising the step of providing an engagement member with said second portion; said engagement member being separable from said second portion.
6.
The method of claim 5, further including the steps of providing an exterior alignment member engageable with said second portion; said exterior alignment member including a sleeve portion for assisting with coaxial alignment of said sleeve portion and said second portion.
7.
The method of claim 6, wherein said exterior alignment member and said second portion have threads and wherein the method further including the step of engaging said threads
