Abstract To solve the problem of cryogenic circumstance (-165 ℃) faced by all-concrete liquefied natural gas(LNG) storage tanks during service, a low-temperature resistant and high-strength concrete (LHC) was formulated. The compressive strength change laws of LHC and ordinary C60 concretes were obtained through the uniaxial and triaxial compression tests under different low temperature conditions. A two-parameter constitutive model was adopted to characterize the deformation characteristics of LHC and C60 concrete under the combined effect of stress and temperature. The test results show that the strength gradually increases as the temperature decreases in the uniaxial test, and the strength of LHC increases from 65.3 MPa (20 ℃) to 96.2 MPa (-165 ℃); the strength of ordinary C60 concrete increases first and then decreases, reaching the maximum value of 78.1 MPa at -140 ℃; the ductility values of LHC and C60 both fluctuate and decrease with the drop of temperature. Under triaxial stress, the strength and ductility of LHC and C60 increase with the drop of temperature. Under the two sets of test conditions, LHC has better cryogenic mechanical properties than ordinary C60 concrete. The research results of this study can provide reference for the application of LHC in all-concrete LNG storage tanks.
