Dicalcium silicate-calcium sulphoaluminate-calcium sulphosilicate raw material, clinker and cement preparation method
The invention discloses a dicalcium silicate-calcium sulphoaluminate-calcium sulphosilicate raw material, clinker and cement preparation method, and relates to the technical field of cement products. According to the invention, the formation temperature of calcium sulphoaluminate and dicalcium silicate is reduced according to the mineralization of compounds such as Na2O, K2O and phosphogypsum in the fly ash red mud and P2O5 and CaF2 in the activating agent. According to the present invention, the activity of dicalcium silicate is improved by combining the activation effect of Fe2O3, B2O3, Al2O3 and other solid solutions on minerals, the formation and the growth of calcium sulphosilicate crystals are ensured by regulating and controlling the ratio and the content of each component in the activator and designing the free gypsum, and the clinker meeting the mineral composition design requirements is prepared while the mineral activity is improved. The stable development of the later strength of the cement is promoted, and the shrinkage of the later strength is avoided.
一种硅酸二钙‑硫铝酸钙‑硫硅酸钙原料、熟料及水泥制备方法,涉及水泥制品技术领域。本发明根据粉煤灰赤泥中的Na2O、K2O、磷石膏和活化剂中的P2O5、CaF2等化合物的矿化作用,降低了硫铝酸钙,硅酸二钙的形成温度。结合Fe2O3、B2O3、Al2O3等离子固溶对矿物的活化作用,提高了硅酸二钙的活性,并通过调控活化剂中各组分的比例和含量以及游离石膏的设计,保证硫硅酸钙晶体的形成和生长,在提高矿物活性的同时,制备出符合矿物组成设计要求的熟料。促进水泥中后期强度的稳定发展,避免了后期强度的倒缩。
