Vertical placement tolerance for reinforcement in slabs-on-ground is ± 3/4 inch from the specified location. For slab thicknesses 12 inches or less, the concrete cover tolerance is - 3/8 inch ...

Lay a grid of rebar spaced four feet apart over the plastic and connect the intersections with tie wire. Divide the concrete slab down the middle with a 2×4 nailed to 1×3 stakes. Align the top ...

based on a lab-tested glass fiber-reinforced polymer rebar-specific punching shear equation, which performs like a steel-reinforced slab at a lower cost. The early deterioration of concrete due to the ...
