ARTIFICIAL STONE MATERIAL
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
【課題】高比重で且つ強度、膨張安定性を十分に満足し、製造時における混練物の流動性を確保して効率的且つ安価に製造可能な人工石材を提供する。【解決手段】骨材である製鋼スラグと結合材である高炉スラグ微粉末を主原料とする鉄鋼スラグ水和固化体からなる人工石材であって、骨材の一部が、溶融した転炉脱炭スラグにノズルから高速空気流を噴射することで得られた風砕スラグからなるとともに、風砕スラグの骨材中に占める割合を１０〜８０容積％とし、乾燥比重を２．５以上とする。風砕スラグは高比重、低吸水率、低膨張性であって、細粒で且つ形状が球形であるため、高比重で且つ強度、膨張安定性を十分に満足する人工石材となり、製造時における混練物の流動性も確保できる。【選択図】図１
