| 摘要 |
The present invention relates to a method for manufacturing light-weight construction material using waste product, and light-weight construction material manufactured thereby, and more specifically, to a method for manufacturing light-weight construction material using waste product such as sewage sludge, remicon sludge, spent foundry sand, power plant ash, incinerator residue, grinding stone residue, discarded asbestos and steel dust, and to a light-weight construction material manufactured thereby. The method for manufacturing light-weight construction material comprises the steps of: (a) manufacturing a waste mixture by adding to a sewage sludge at least one type of waste product selected from the group consisting of remicon sludge, waste foundry sand, discarded asbestos and power plant ash, or by adding to a remicon sludge at least one type of waste product selected from the group consisting of incinerator residue, grinding stone residue, waste foundry sand, discarded asbestos, steel dust and power plant ash; (b) adding to the waste mixture an additive selected from the group consisting of feldspar, bentonite, zeolite, loess, mica and agalmatolite, and then mixing to manufacture a mixture containing the additive; (c) manufacturing a molded material by molding the mixture containing the additive; and (d) manufacturing light-weight construction material by plastic-forming the molded material in a furnace. |
