Document Type and Number:
Japanese Patent JP7208077
Kind Code:
B2
Abstract:
To provide a coal ash solidified matter capable of achieving effective use of waste aiming at organization of a recycling-oriented society, and great suppression of manufacturing cost, by reducing raw material cost by enabling recycle of waste into the whole raw material.SOLUTION: A solidified matter is obtained by kneading coal ash discharged from a power station, shell powder containing calcium carbonate in waste shellfish containing scallop shells or oyster shells, blast-furnace slag (metal slag), lime, and gypsum dihydrate, and by subjecting them to a hydration reaction, to thereby reduce raw material cost, and reduce manufacturing cost greatly.SELECTED DRAWING: Figure 1
