(57) [Summary] [Purpose] In order to have good fluidity at room temperature, no change with time during storage in a wet state, pouring work is possible, and heat curing to facilitate curing at 60 to 100 ° C. Thermosetting indefinite shape, such as shape retention and deframing by low temperature heating, heat curing in a short time, high dry strength without deterioration at intermediate temperature, good corrosion resistance, etc. Satisfaction of the characteristics required for refractories. [Structure] 100% by weight of a particle size-adjusted refractory aggregate containing 10 to 30% by weight of fine powder of 44 μm or less, and 0.1 to 0.1% of a phenol resin having a softening point of 70 to 200 ° C. as a binder. 10% by weight and polysaccharide heat-sensitive gelling agent 0.1-10% by weight And 0.5 or less of soluble sodium phosphate and / or condensed aluminum phosphate as a poorly soluble binder. After blending up to 3% by weight, adding water, kneading and pouring 60 Heat to ~ 100 ° C to cure. |
