采用化学分析、X射线衍射等测试手段研究了掺杂离子对含硫铝酸钙(C_4A_3(S))硅酸盐水泥熟料烧成及矿物组成的影响.研究结果表明:要制备含C_4A_3(S)矿物硅酸盐水泥熟料,应在生料中掺入合适的杂质离子;适量的掺杂离子能降低含C_4A_3(S)矿物硅酸盐水泥熟料的烧成温度,大幅度促进熟料中f-CaO的吸收,改善生料的易烧性,在低温煅烧温度(1300 ℃或1350 ℃)下成功制备了含C_4A_3(S)矿物硅酸盐水泥熟料.
The influence of additive on the burning and minerals composition of cement clinker containing calcium sulphoaluminate were researched by chemical analysis and X-Ray diffraction.The results show that the additive must be added in the raw meal for the preparation of the clinker containing calcium sulphoaluminate. The suitable amount of additive can decrease the burning temperature of the clinker containing calcium sulphoaluminate, promote the adopt of f-CaO and improve the burnability of the raw meal. At the relative low temperature (1300 ℃ or 1350 ℃), the clinker containing calcium sulphoaluminate can be preparaed successfully.
