METHOD OF PRODUCING ARTIFICIAL STONE MATERIAL
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.
【課題】製鋼スラグおよび高炉スラグ微粉末を含む原料と水の混練物を水和硬化させた後、この水和固化体を破砕して人工石材を製造する方法において、低比重の人工石材を製造できるとともに、製品歩留まりを高めて製造コストを低減させることができる製造方法を提供する。【解決手段】水和固化体の破砕物を篩い分けし、篩上の破砕物を製品石材とするとともに、篩下の破砕物を水和固化体の原料の一部として再利用する。篩下の破砕物は、製鋼スラグに較べて比重が小さいため、この篩下の破砕物を、骨材である製鋼スラグの一部または全部の代替材として原料に配合することにより、製造される人工石材の比重を小さくすることができ、しかも、製品歩留まりも向上する。【選択図】図１
