Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars and is usually embedded passively in the concrete before the ...

If reinforcing mesh is required, cut it to fit inside the formwork allowing 5 cm clearance between the formwork and end of the bars so the reinforcing will be completely covered in concrete. Use plastic bar chairs placed closely together to support the reinforcing mesh and hold it in the centre of the slab.
