Method for modifying sulphoaluminate cement

摘要: The invention discloses a method for modifying sulphoaluminate cement. comprises the following steps of adopting an intermediate mineral (calcium sulphosilicate) formed in traditional firing process cement clinker, clinker as base material, adding gypsum regulator, mixing and grinding to prepare modified disclosed by has beneficial effects that problem reduction later strength can be effectively improved, andlong-term mechanical properties application range expanded; simultaneously, preparation sulphosilicate), silicates waste slags with high calcium sulfate content consumed, so advantages saving energy, reducing consumption cost being convenient use like.
