MONOLITHIC REFRACTORY

摘要

Provided is a monolithic refractory which rarely deteriorates in strength at a high-temperature range of, for example, over 1,000°C irrespective of an organic binder being used as a bonding agent. The monolithic refractory of the present invention comprises an organic binder, and fireproof powder comprising a rough grain area with a grain diameter of at least 1mm and a fine grain area with a grain diameter of less than 1mm. The fine grain area is mixed with burning olivine, and the amount of the organic binder used ranges from 1 to 20% by mass in terms of outer percentage based on 100% by mass of the fireproof powder.
