<p>The present invention provides a method of manufacturing an artificial aggregate using wasted water sludge and the method includes: a step of preparing a raw material by mixing a composite comprising 40 to 60 wt% waste water sludge powder, sand 5 to 20 wt%, clay 10 to 20 wt%, gypsum 10 to 20 wt%, iron 5 to 10 wt%, ash 1 to 2 wt%, fiber 5 to 10 wt% and calcium 1 to 2 wt%; a step of pressurization-forming the raw material by inserting the raw material into a press; and a step of sintering the formed material in a sintering furnace at temperature of 1100 to 1300°C for 12 to 36 hours and cooling the sintered material. [Reference numerals] (AA) Mixing raw materials (sludge, sand, clay, gypsum, iron, ash, fiber, calcium, and other additives);(BB) Pressurization-molding using a press;(CC) Drying pressurization-molded materials;(DD) Sintering the dried molded materials</p> |
