摘　　要：利用DTA,XRD,SEM等方法,研究了石膏对新型白色阿利尼特水泥的早期水化产物形成的影响。结果表明,石膏能明显加快该水泥水化产物的形成,提高其强度,该水泥的主要早期水化产物为C-S-H凝胶和Ca(OH)_2,还有少量的C_3A·3CaSO_4·32H_2O和C_3A·CaCl_2·H_(10)。The influence of gypsum on the forming of early hydrated product of new white alinite cement added gypsum was studied by means of DTA, XRD and SEM . The results show that gypsum can accelerate the formation of the main early hydrated products and enhance the strength of hardened paste. The main early hydrated product of this kind of cement is C - S -H gel, Ca(OH)2, and a spot of C3 A · 3CaSO4 · 32H2O and C3 A · CaCl2 · H10.
