A concrete slab construction joint and a continuous pour control joint function in slab-on-grade applications. The construction joint features a keyed profile with two continuous number four rebars at the edges, a bonded first pour face coated with bond breaker before the second pour, and continuous dowels matching the slab reinforcement size and spacing with one end greased. The control joint details a saw-cut extending to twenty-five percent of the slab thickness within twelve hours of placing concrete, with a maximum spacing of ten feet unless otherwise noted and two continuous number four rebars running along the edges.
