| titleOfInvention | Fine aggregate for lightweight refractory concrete and method for producing lightweight refractory concrete using the same |
| abstract | The present invention provides a fine aggregate for lightweight refractory concrete that is useful for producing lightweight refractory concrete having excellent fire resistance. A fine aggregate having a diameter of 5 mm or less and containing water Wi inside and a surface covered with surface water Wo is obtained by removing and classifying ultrafine particles by washing ash with a fine particle size. The fine aggregate is dried at 670 to 730 ° C. to remove the surface water Wo and generate a void S from which a part of the moisture Wi is removed. Thereafter, heat treatment is performed at 800 to 850 ° C. to increase the proportion of the amorphous component, and the void S containing residual moisture is left inside. Thereafter, the surface air bubbles W of the fine aggregate are closed with a coating material, and further thickened by adding cement and water, and the surface of the fine aggregate is adjusted to pH by OH- ions released from the cement. 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. [Selection] Figure 1 |
