The invention provides a novel cement mixed material, which is characterized by being prepared from inorganic matter ingredients of paper making sewage dust, alkali recovery paper making white mud, ink sludge and ecological sludge in parts by weight:, the paper making sewage dust accounts for 30 to 50 parts; the alkali recovery white mud accounts for 20 to 40 parts; ink sludge and ecological sludge account for 10 to 40 parts; diatomite accounts for 10 to 30 parts; the inorganic matter ingredients of the ink sludge and the ecological sludge are calcined for 4 to 6h at 400 to 600 DEG C. The mixed material prepared from the inorganic matter ingredients of the paper making sewage dust, the alkali recovery paper making white mud, the ink sludge and the ecological sludge has the advantages thatthe cement performance can be improved; the energy is saved; the emission is reduced; the utilization rate of solid waste is improved; the environment is protected; daily decreased conventional mixedmaterials such as gypsum and limestone can be replaced; the production cost is greatly reduced.
