SECTION 5 - REINFORCEMENT
SECTION 5 REINFORCEMENT 5-1 SECTION 5 - REINFORCEMENT - GALVANIZED REINFORCEMENT Galvanized REINFORCEMENT shall be used in all locations. Galvanizing provides corrosion resistance by adding a sacrificial coating of zinc to the REINFORCEMENT . The zinc is consumed by the movement of electrons and, therefore, does not expand to the same magnitude that bare metal expands as it corrodes. Therefore, concrete cracking and spalling due to REINFORCEMENT corrosion is delayed until the zinc coating has been fully consumed. Stainless steel and stainless steel clad reinforcing steel is also available. These types of steel should only be used in highly corrosive marine environments with approval from the DSD. Refer to the NYSDOT Standard Specifications for the mechanical requirements of stainless steel reinforcing.
Specified bar lengths are limited due to fabrication and coating constraints and design considerations. This allows for the most econom ical …
