Ultra-low temperature concrete is mainly used for LNG storage tank of concrete structures, likewise low temperature refrigerated warehouses. Especially for liquefied natural gas storage tank wall body, because of that liquefied natural gas (LNG) is cooled to a ultra-low temperature of about -163℃, it will be subject totemperature stress caused by temperature difference between inside and outside, cold and hot impulsion caused by stored liquid drainage and its effect on the over and over again, and as the underground storage tank at ordinary times is also under pressures of huge load like the frozen earth pressure and frost heaving force besides the soil pressure.
