A manufacture device and a manufacturing method of construction material

Japanese Patent JP6061289

B2

PROBLEM TO BE SOLVED: To effectively utilize fly ash and the like as a construction material for a cement admixture and the like by suppressing an influence on an appearance of a product to be minimized.SOLUTION: A production apparatus 1 of a construction material comprises: a plasma irradiation device 3 irradiating a raw material A1 (fly ash and the like) containing unburned carbon for the construction material with plasma; and a decarbonation device to remove the unburned carbon from the raw material containing the unburned carbon for the construction material. The plasma irradiation device can irradiate the raw material for the construction material after the treatment of decarbonation with plasma. The unburned carbon existing in the raw material for the construction material is reformed from hydrophobicity to hydrophilicity by irradiating the raw material for the construction material with plasma. The floating of the unburned carbon on the surface of the product when a construction material A2 after reforming is utilized can be prevented.
