ACI C-20-92 PDF Download

The ACI C-20-92 standard is a collection of papers that address various aspects of repairing and rehabilitating concrete structures. The standard covers a wide range of topics including roof top parking slab replacement, repair methods for salt-damaged reinforced concrete structures, quality workmanship, headworks rehab, rehabilitating an elevated roadway bridge, and reservoir rehab.

One key focus of this standard is addressing the repair and replacement of rooftop parking slabs. This is a critical aspect as parking slabs are subjected to heavy loads and often face deterioration over time. The standard provides guidance on how to assess the condition of the slabs, determine the appropriate repair or replacement methods, and ensure quality workmanship.

Another important area covered by the standard is the repair of salt-damaged reinforced concrete structures. Salt can cause corrosion of the reinforcing steel, leading to structural deterioration. The standard offers recommendations and techniques for repairing and rehabilitating these structures to ensure their durability and longevity.

Additionally, the standard emphasizes the importance of quality workmanship in the repair and rehabilitation process. It provides guidelines for contractors and engineers to follow to ensure that the repairs and replacements are carried out effectively and meet the required standards.
