Low-temperature preparation method of sulfur silicate-belite-sulphoaluminate cement

摘要: The invention discloses a low-temperature preparation method of sulfur silicate-belite-sulphoaluminate cement. comprises the following steps: (1) putting raw materials into planetary ball mill and uniformly mixing finely grinding, wherein comprise an aluminum-silicon material, aluminum calcium silica material industrial gypsum; (2) pressing mixed in step cake placing high-temperature electric furnace; calcining at temperature 700to 1200 DEG C; then taking out quenching; (3) grinding product obtained by powder; (4) with dihydrate gypsum to prepare According disclosed invention, common wastes including gehlenite containing intermediate phase other aluminate aredirectly used as do not need be subjected modification or treatment; treatment cost is reduced utilization rate isimproved. early-stage greatly reduced; meanwhile, environment problem cased solved.
