Disclosed are a soundproof construction composition using waterworks sludge and a method for preparing the same. The soundproof construction composition using waterworks sludge manufactured by mixing 22% by weight of a first processed clean water sludge made by firing waterworks sludge for 3-5 hours at 800°C-850°C, with 18% by weight of clay, 36% by weight of terra alba, 14% by weight of agalmatolite, and 10% by weight of dolomite to obtain a body; mixing 31.5% by weight of the body with 2.3% by weight of calcined gypsum, 11.3% by weight of cement, 0.05% by weight of aluminum powder, 0.5% by weight of starch, 0.5% by weight of titanium dioxide to prepare a powdery mixture; and mixing the powdery mixture with 10.8% by weight of phosphoric acid and 43.05% by weight of water. |
