中文摘要：

利用X射线衍射结合Rietveld拟合精修、X射线荧光及微量热分析等，研究了在Na、Mg等熟料阿利特典型固溶组分作用下，不同形式磷酸钙盐引入P^5＋掺杂对阿利特烧成、结构及水化活性的影响。结果表明：不同磷酸钙盐对阿利特烧成影响存在差异，磷酸氢钙对烧成阻碍作用最小，磷酸钙次之，磷酸二氢钙最大，这可能与三种化合物的熔点不同有关；不同磷源P^5＋对阿利特多晶态稳定作用相近，1.0%掺量P2O5可完全稳定R型阿利特；磷酸氢钙具有较低的挥发率，低掺量（〈 1.0%）下更有利于稳定R型；P2O5在阿利特中的固溶极限约为1.0%，掺量低于1.0%时，R型阿利特晶格常数随P2O5掺量基本呈线性变化；不同磷源P5＋掺杂均使阿利特初始水化活性降低，水化40 h后活性升高，其中R型阿利特样品3 d后水化活性高于其他样品。

英文摘要：

The formation, crystal structure and hydration activities of alite modified by the introduction of varying forms of calcium phosphate under different dosage and some impurities like Na, Mg, etc. into raw mix, were examined. The effect of phosphorus oxides （P2O5） was analyzed by X-ray diffraction combined with Rietveld method, X-ray flourescence spectrometry and isothermal calorimetry. Results showed that the positive effecting sequence of low content （≤0.6%, mass fraction） of calcium phosphates on alite formation from high to low is CaHPO4, Ca3（PO4）2, Ca（H2PO4）2, and this may be due to the different melting temperatures. Diverse forms of calcium phosphates had a similar behavior on the stabilization of high-temperature forms of alite, and addition of 1.0% P2O5 made rhombohedral （R） alite stable at room temperature. In addition, lower concentration of CaHPO4 had more beneficial effect on stabilizing type R alite polymorphism as a result of its low volatility. The lattice parameters of the R polymorph with the content of P2O5 was essentially linear, up to the limits of P2O5 of 1.0%. The early hydration rate of samples doped with P5＋ from varying phosphates were reduced while the hydration after 40 h was increased. R-type alite had the highest hydration activity in all samples after 3-day age.
