One such criterion is the permeability of concrete as it controls the rate by which LNG is lost from the primary container. The permeability of concrete to LNG at cryogenic temperatures is likely dominated.

Generally, the permeability and the CTE are lower while the tensile strain capacity and bond strength to reinforcement are greater for concrete at cryogenic temperatures versus concrete at ambient.
