Title:
A manufacturing method of an artificial stone
Document Type and Number:
Japanese Patent JP6160833
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of producing an artificial stone material by subjecting a kneaded matter of water and a raw material containing steel slag and blast furnace slag fine powder to hydration hardening, and crushing a hydrated solidified body, the method being capable of producing an artificial stone material having a low specific gravity and enhancing a production yield to reduce production costs.SOLUTION: A crushed matter of the hydrated solidified body is sifted into an oversized crushed matter to be used as a product stone material, and an undersized crushed matter to be reused as part of a raw material of the hydrated solidified body. The undersized crushed matter has a smaller specific gravity than steel slag. Therefore, a specific gravidity of an artificial stone material to be produced can be decreased and a product yield can also be improved by blending the undersized crushed matter into the raw material as an alternate material of part or all of the steel slag being an aggregate.
