Review Report


1. Limit Z for beams (w = 0.33mm, 0.4mm)
    a). Exterior exposure: [Z] = 25,000 N/mm
    b). Interior exposure: [Z] = 30,000 N/mm

2. Limit Z for slabs
    a). Exterior exposure: [Z] = 22,000 N/mm
    b). Interior exposure: [Z] = 27,000 N/mm

3. For epoxy coated reinforcement, Z = 1.2[Z]

4. Skin Reinforcement:

    a). Ask = 0.008 (or 0.01)Acs
     Acs - the area of concrete in strips along the exposed side faces
    b). Max. spacing = 200mm
