    Abstract: A refractory mortar cured material is formed in the surface or joint portions of a ceramic refractory material, such as fire bricks used in the lining of melting furnace or firing furnace used at high temperature, and includes ceramic particles with an inorganic binder having silanol group that are kneaded together with water. The kneaded mortar is applied on the surface of a ceramic base material. The average particle size of ceramic particles in the refractory mortar is 10 to 50 μm, and the difference between the 90% particle size and the 10% particle size is 10 μm or more to 60 μm or less. The average pore size of the refractory mortar cured material is 5 to 25 μm, and the width of pore size distribution is 20 to 80 μm, so that the cracks are suppressed. In addition, the bulk density is 0.9 to 1.5 g/cm3.

    Abstract: The non-settling refractory mortar of the invention contains 100 parts of ceramic powder such as cordierite, mullite, alumina, or silicon carbide, 0.5 to 1.5 parts of clay mineral, and colloidal oxide solution, in which the Ca content in total solid component is defined at 0.01 to 0.5% as converted to oxide so as to be provided with thixotropic property. As a result, the coating performance is not lowered if stored for a long period after kneading, the dimension change rate after coating is small, and cracks or gaps are not formed on the coat surface. The median diameter of ceramic powder is preferred to be 10 to 50 μm, and in order to reduce the dimension change rate after coating, the content of particles of 0.1 to 5 μm in ceramic powder is desired to be 1 to 20%.
