Method for preparing calcium sulphosilicate-calcium sulphoaluminate cement
The invention discloses a method for preparing calcium sulphosilicate-calcium sulphoaluminate cement, which comprises the following steps: step 1, mixing a raw material containing aluminum and silicon with limestone and dihydrate gypsum, grinding and sieving to prepare a cement raw material; wherein the mass ratio of the aluminum element to the silicon element in the raw material containing aluminum and silicon is greater than 0 and less than or equal to 4; the raw materials containing aluminum and silicon are 67-78 parts by weight, the limestone is 20-34 parts by weight, and the dihydrate gypsum is 38-45 parts by weight; 2, the cement raw material obtained in the step 1 is placed in a high-temperature furnace, the temperature is increased to 1000 DEG C to 1200 DEG C, heat preservation is conducted for 30 min to 120 min within the temperature range, calcination is conducted, cement clinker is obtained, then the cement clinker is placed in air to be cooled to the room temperature, and the calcium sulphosilicate-calcium sulphoaluminate cement is obtained.
本发明公开了一种制备硫硅酸钙‑硫铝酸钙水泥的方法，包括如下步骤：步骤1：将含有铝硅的原料与石灰石、二水石膏混合，粉磨后过筛，制成水泥生料；其中，0＜含有铝硅的原料中铝元素和硅元素的质量比≤4；按重量份数计算：含有铝硅的原料为67~78份、石灰石为20~34份、二水石膏为38~45份；步骤2：将步骤1得到的水泥生料置于高温炉内，升温至1000℃~1200℃并在该温度范围内保温30~120min进行煅烧，得到水泥熟料，然后将水泥熟料置于空气中冷却至室温，得到所述硫硅酸钙‑硫铝酸钙水泥。
