Concrete slab joint configurations for sequential pours. The construction joint features a keyed profile with continuous dowels matching the slab reinforcement size and spacing, with one end greased and a bond breaker painted on the slab edge before the second pour. Two continuous number four rebars are provided at the slab edges. The control joint incorporates a sawn cut measuring twenty-five percent of the slab thickness executed within twelve hours of placing concrete, alongside continuous edge reinforcement.
