Zusammenfassung:	An apparatus for forming concrete includes a form having a slot configured to closely receive a plate. The slot is defined by one or more annular surfaces having central axes perpendicular to a direction in which the slot receives the plate. A method for forming same includes providing a sheet of form material; disposing a release layer on the sheet; cutting the sheet into a plurality of forms having a predetermined form height; and cutting a slot in each of each of the plurality of forms. Another apparatus for forming concrete includes a plate having a first portion and a second portion. A coating is disposed on the first portion. When disposed in a joint defined by a first volume of concrete and a second volume of concrete, the first volume of concrete adheres only to the coating and the second volume of concrete adheres only to the second portion. A method for forming concrete includes providing a plate having a coated first portion and a second portion; providing a form having a slot configured to closely receive the second portion; inserting the second portion in the slot; positioning the form to receive concrete; pouring a volume of concrete on the form and the first portion; curing the volume of concrete and defining cured concrete; and removing the form from the cured concrete. The plate remains in the cured concrete.
