Abstract The mechanical performance of prestressed concrete (LHC) as a material for liquefied natural gas (LNG) storage tanks is significantly degraded in the ultra-low temperature (-165 ℃) environment. The perdormance of low-temperature concrete was studied and evaluated in this paper, and the pore structure characteristics and mechanical properties of LHC after low-emperature cycles are analyzed. The results showed that the number of pores at 105 nm—104 nm in LHC matrix is relatively small, and the volume of pores, pores and total porosity in LHC are lower than those in C60 concrete. After cryogenic cycling, the LHC matrix and the internal structure of C60 concrete were damaged to a certain extent, and all the mechanical parameters showed a downward trend. Compared with C60 concrete, LHC has excellent mechanical performance at ultra-low temperature environment.
