The present invention relates to a binder mixture in which 1 to 20% by weight of stone dust, 10 to 40% by weight of fly ash and 50 to 80% by weight of floor ash are mixed, using a non-ferrous separator using a vortex and magnetic force to select ferrous and non-ferrous; pulverizing the non-ferrous materials of the selected binder mixture; And with respect to 100 parts by weight of the non-ferrous material of the pulverized binder mixture, as a cement-based eco-friendly inorganic binder composition for recycled raw materials produced by a manufacturing method comprising the step of mixing 0.1 to 10 parts by weight of a performance improvement admixture, The performance improvement admixture is based on 100 parts by weight of calcium sulfoaluminate, 80 to 100 parts by weight of anhydrite, 50 to 70 parts by weight of sodium sulfate, 1 to 20 parts by weight of zinc oxide, 1 to 20 parts by weight of silicoaluminophosphate, tungsten disulfide. 5 to 10 parts by weight and 0.1 to 10 parts by weight of biocellulose powder; By actively utilizing industrial by-products such as incineration ash and stone dust, and not adding cement, it is possible to reduce carbon dioxide emissions and fundamentally prevent secondary soil contamination by heavy metals such as hexavalent chromium. It relates to a cementless-based eco-friendly inorganic binder composition for a recycled raw material that can be usefully used as a recycled raw material. |
