选择几种不同生料进行配方,烧制不同含量硅酸二钙水泥熟料,在煅烧过程中通过阴离子掺杂来研究对熟料易烧性能的影响,并添加稳定剂B2O3使贝利特保持活性较高的晶型;运用XRD、岩相分析、SEM等测试手段,初步探讨了离子掺杂对高强低钙硅酸盐水泥熟料煅烧和水化性能的影响. 主要结论是,最佳的煅烧温度为1 350℃,稳定剂的加入可以促进熟料中的稳定存在;其次,当煅烧温度在1 400~1 450℃,w(C2S)含量在45%、w(C3S)含量30%时,熟料矿物结晶完整,矿物形貌最好,其早龄期的水化产物量也最多.

With view to the new requirements of energy-saving emission reduction and low-carbon economy, the research and development ( R&D ) of low calcium cement has great significance . This paper probes into firing different content belite cement clinkers and proportioning different raw materials, which finds out that the burnability of clinkers can be improved remarkably by ions adopting and the crystal form can be stabilized by adopting B2O3. Using chemical reagent and industrial raw materials, by chemical analysis, XRD (X-ray diffraction), lithofacies analysis and SEM, effects of ions doping on calcining and hydration properties of high strength low calcium portland clinker are discussed in details. Results show that the most suitable temperature of clinkers sintering is 1 350℃, can be in steady existence by adding stabilizers, and fossil has its best morphology under the condition of complete mineral crystallizing cement when the calcination temperature ranges from 1 400℃ to 1 450℃ with w(C2S) being 45% and w(C3S) 30% of the content.
