A non-slump, high-density, low-moisture castable composition in which the amount of calcium aluminate cement used as a binder is reduced to the maximum to improve mechanical properties at high temperatures such as corrosion resistance and hot strength. , And provide the construction method. SOLUTION: A calcium aluminate cement in which the amount of calcia component contained in a calcium aluminate cement is 0.2 to 1% by weight in a solid content of 100% by weight, a total of 6 clay and siliceous fine particles. 100% by weight of solid content consisting of -15% by weight, 0.01-0.5% by weight of peptizer and the balance of refractory aggregate and fine powder to achieve consistency that can be pumped A non-slump ultra-low cement-based bond castable composition comprising a pumpable first component kneaded with a sufficient amount of water, and a second component flocculant added to the first component during construction; and , Its construction method.
