Sulphoaluminate cement and preparation method thereof
The invention discloses sulphoaluminate cement. The sulphoaluminate cement is characterized by containing 5%-35% by mass of calcium sulphosilicate mineral. The invention further discloses a preparation method of the sulphoaluminate cement. The preparation method is characterized in that the fired clinker contains calcium sulphosilicate, and comprises the following steps of firstly, calcining a raw material according to a proper calcination process in preparation; carrying out secondary calcination according to the set calcination temperature and heat preservation time; and grinding secondarily calcined cement clinker and additive gypsum to prepare the sulphoaluminate cement. The sulphoaluminate cement is simple to prepare, convenient to implement and low in cost; the later strength shrinkage problem of the sulphoaluminate cement can be improved; meanwhile, the calcium sulphate content can be improved; the silicate waste residues with high calcium sulphate content are digested; and the production and application ranges of the sulphoaluminate cement are expanded.
