PROBLEM TO BE SOLVED: To efficiently and inexpensively provide an artificial stone material at high specific gravity sufficiently satisfying strength expansion stability, and securing the fluidity of a kneaded matter upon production.SOLUTION: Provided is an artificial stone material made of a steel slag hydrated solid using steel making slag as an aggregate material and high furnace slag fine powder as a binder, in which a part of the aggregate is made of hydrated slag obtained by jetting a high speed air flow to melted furnace decarburized slag from nozzle, further, the ratio occupied in the aggregate of the hydrated slag is 10 to 80 vol%, and its dry specific gravity is 2.5 or more. The hydrated slag has high specific gravity, low water absorption and low expansibility, and being fine-grained and also whose shape being spherical, thus an artificial stone material having high specific gravity and also sufficiently satisfying strength and expansion stability is made, and the fluidity of a kneaded matter upon production can be secured as well.SELECTED DRAWING: Figure 1 |
