How Far Apart Should Rebar Be Placed In Concrete Slab at Tommy Larkin blog

How Far Apart Should Rebar Be Placed In Concrete Slab. Rebar that's too far apart lacks the tensile strength to reinforce the concrete sufficiently, but when it's too close, the cement in the slab won't mechanically bond to develop its own tensile strength. For driveways and patios, a #3 rebar (3/8 inch in diameter) is generally sufficient, while for walls, piers, and columns, a #4 rebar (1/2 inch). To ensure maximum effectiveness, rebar should ideally be positioned near the top of the concrete slab. Rebar should be placed in a grid. Rebar should be placed evenly throughout the project. As a rule of thumb, the spacing of rebars should be approximately three times the thickness of the slab, or closer if the load demands it. For a flat slab, such as a driveway, consider placing the rebar in an 18 inch grid spacing, keeping the edge rebar at the same distance from each.
