Objective
To provide the technical data required to support the design of unlined, as well as lined, prestressed concrete facilities for the storage of liquefied natural gas (LNG).
Results are available which show the influence of cryogenic temperatures on a range of concrete properties including: permeability; compressive strength; tensible strength and strain capacity; flexural strength and strain capacity; elastic modulus; creep; bond to steel; thermal contraction; specific heat; resistance to thermal cyling.
Data on properties of steel for rebar and prestressing has also been obtained including: elastic modulus; yield stress; ultimate tensile stress; strain at failure; impact transition temperature (charpy and full bar tests).
Light-concrete was identified as being particularly suitable for cryogenic applications and the performance of light-weight prestressed beams has been recorded.
Tests have been carried out to identify the concreting materials and mix proportion most suited to cryogenic applications. Selected concretes were comprehensively tested at temperatures down to -165 deg. C to determine the engineering properties required for design. A range of reinforcing steels and prestressing systems were also investigated. Finally, prestressed concrete elements were tested under conditions of live and thermal loading.
