| titleOfInvention | Fine aggregate for lightweight refractory concrete, method for producing the same, and method for producing lightweight refractory concrete using fine aggregate for lightweight refractory concrete |
| abstract | An object of the present invention is to provide a fine aggregate for lightweight refractory concrete which is useful for producing lightweight refractory concrete excellent in fire resistance. SOLUTION: A fine aggregate having a diameter of 5 mm or less, which contains water Wi inside and is covered with surface water Wo, is obtained by removing ultrafine particles by washing ash having a small particle diameter and classification. The fine aggregate is dried at 670 to 730 ° C. to remove the surface water Wo and generate a void S in which a part of the water Wi is removed. Thereafter, heat treatment is performed at 800 to 850 ° C. to increase the ratio of the amorphous component and leave a void S containing residual moisture therein. Thereafter, the blocking process of the surface layer of the bubbles W of fine aggregate in the coating material, further increasing to viscosity by adding thereto cement and water, to the surface of the fine aggregate, OH released from the cement - pH by ion Is increased to form a film C having a high viscosity, and finally a fine aggregate having a water content of 3 to 5% by weight is obtained.
