Abstract:

To investigate the mechanical properties of concrete under the leakage condition for a liquefied natural gas storage tank, cryogenic freeze-thaw cycle tests were performed under liquid nitrogen refrigeration and water immersion melting. The effects of the cryogenic temperature, freeze-thaw cycle, pre-crack, and addition of steel fiber on the compressive strength, flexural strength, and splitting tensile concrete strength were analyzed. The experimental results show that the width of pre-cracks tends to expand after freeze-thaw cycles. When the freezing temperature is -80 ℃, the relative width of the pre-cracks expands by 1 to 2 times. However, when the freezing temperature is -120 ℃, the relative width of the pre-cracks expands by 2 to 5 times. Compared with the specimens without steel fibers, the specimens with steel fibers can still maintain a relatively complete appearance structure after the mechanical property tests. The compressive strength, flexural strength, and splitting tensile concrete strength decrease with the drop in the freezing temperature. After adding steel fibers, all of the three strengths increased.
