Abstract:
I’m designing a foundation to support a liquefied natural gas (LNG) tank in a marine environment, and I want to use epoxy-coated reinforcement (ECR). In case of a major spill, the pier will be exposed to LNG at cryogenic temperatures. However, per Section 4.7.1 of ACI 376-11,1 deformed reinforcement at service temperatures equal or greater than 0°F (–18°C) must be uncoated. How can I meet the code and protect the reinforcement?
