Abstract: A concrete construction includes a formed concrete slab having at least one control joint formed into a surface of the slab to control the location of stress cracks as the slab cures. A control joint protective strip is removably received in the control joint and has a head portion which overlays upper edges of the control joint. The control joint protective strip further includes a stem portion which is configured to engage frictionally interior side walls of the control joint when the stem portion is inserted into the control joint.
