<p>PURPOSE: An artificial soil composition using industrial by-products for recovering an abandoned quarry mining and a manufacturing method thereof are provided to prevent environmental contamination by blocking bad small of end products through the use of a highly functional deodorizing agent. CONSTITUTION: A method for manufacturing artificial soil using industrial by-products for recovering an abandoned quarry mining comprises the steps of: (S1) mixing 30~50 parts by weight of alumino-silicate-based paper sludge incineration ash and 30~50 parts by weight of fly ash to prepare a first mixture, wherein the alumino-silicate-based paper sludge incineration ash has a specific surface area of 2,000 cm^2/g or more and fly ash has pozzolanic reaction; (S2) mixing 5~10 parts by weight of calcium oxide (CaO), 0.5~3 parts by weight of solidifying promoter, and 5~15 parts by weight of at least one inorganic binder, wherein the inorganic binder is selected from the group consisting of fine blast-furnace slag powder or one kind of Portland cement and three kinds of high early strength cement; (S3) mixing 5~10 parts by weight of a second mixture and inorganic acid and 5~20 parts by weight of H2O to 100 parts by weight of sewage/wastewater and sludge to prepare a third mixture; and (S4) mixing 1~5 parts by weight of deodorizing agent and 30~60 parts by weight of waste stone powder to the third mixture to prepare a forth mixture, wherein the forth mixture are transferred to a curing tank.</p> |
