Zusammenfassung:	The invention discloses an autoclaved brick prepared with dredged sludge and a preparation method thereof. The autoclaved brick is prepared with the following materials in part by weight: 42 to 52 parts of dredged sludge, 10 to 14 parts of carbide sludge, 9 to 12 parts of cement, 10 to 20 parts of fly ash, 8 to 12 parts of steel slag, 3 to 4 parts of gypsum, 0.2 to 0.8 parts of dry enteromorpha sections (0.5mm to 1.5mm in width and 2mm to 8mm in length), 0.4 to 0.7 parts of property regulator and 0.2 to 0.5 parts of density regulator. In the invention, dredged sludge in the sea and rivers are used as main material, an optimal formula is developed after multiple times of experiments, the produced dredged sludge autoclaved brick has high compressive strength and break strength, and the exploitation and recycling of waste resource are realized. The invention has the advantages of simple and abundant materials, low material cost and the like, and is easy to operate.
