ASTM WK59016

    New Specification for Deformed and Plain Steel Bars for Concrete Reinforcement at Cryogenic Design Temperatures

    (What is a Work Item?)

    Developed by Subcommittee: A01.05 | Committee A01 | Contact Staff Manager


    1. Scope

    This specification covers deformed and plain steel bars in cut lengths for concrete reinforcement intended for applications where additional mechanical properties are required for compatibility with exposure to cryogenic temperatures, down to -320F [-196C].


    concrete reinforcement; deformations (protrusions); steel bars; cryogenic; rebar: :


    Primary use is for concrete reinforcement of liquid natural gas tanks. Tanks are typically an inner liner made of a cryogenic duty plate steel. The inner tank is then "reinforced" with reinforced concrete. The primary purpose of the concrete is containment in the event the inner lining ruptures. The material must be guaranteed to perform at the lowest temperature to which it will be exposed. The Alternative to this material is to either use fully austenitic stainless steel reinforcement or to use grade 40 steel and over build the structure to compensate for lack of performance guarantee with raw mass. The standard being proposed is the most desired solution for the design and build of these types of storage tanks.

    The title and scope are in draft form and are under development within this ASTM Committee.
