Abstract
During positioning of the cylindrical, open ended, outer member relative to a point on a slab form, a cap member may be used to cover the top and support a location determining member. The length of the outer member is adjustable to the thickness of the concrete layer to be poured. A cylindrical inner member, with a closed bottom and an open top, is inserted into the outer member. As the concrete is poured, it is received in the inner member and forms the test core. After the concrete sets, the inner member is removed, resulting in a hole in the concrete. The cap member is alternatively adapted to close the bottom of the outer member, prior to mounting the outer member on the form, to permit the hole to be subsequently filled, if the form has been removed.
