采用Rietveld法X射线粉末衍射、电感耦合等离子体发射光谱、热释光和等温量热法研究了碱金属氧化物掺杂对硅酸三钙C3S晶体结构、缺陷和水化行为的影响。所有样品均稳定为T1型C3S。C3S晶体结构的变化主要通过晶格参数的变化来监测，晶格参数的变化与碱金属的掺入浓度和取代类型密切相关。虽然碱金属以微量掺入C3S中，但对C3S的热释光和水化行为有显著影响。初始水化活性显着增加，并高度相关的辐射诱导的热释光峰的强度在低温下，由于其直接相关的缺陷。碱金属对Ca的替代作用产生的氧空位可以很好地解释C3S初始水化加速的原因。
Influences of alkali oxides doping on the crystal structure, defects and hydration behavior of tricalcium silicate C3S were investigated by X-ray powder diffraction with the Rietveld method, inductively coupled plasma optical emission spectroscopy, thermoluminescence and isothermal calorimetry. All the samples were stabilized as T1 form C3S. Changes in the crystal structure of C3S could mainly be monitored by changes in lattice parameters, which were closely correlated with the incorporation concentration and substitution types of alkalis. Although alkalis were incorporated at trace level in C3S, the thermoluminescence and hydration behavior of C3S were significantly influenced. Initial hydration activity was dramatically increased and highly related to the intensity of the irradiation-induced thermoluminescence peaks at low temperatures due to their direct correlation with defects. The oxygen vacancy sites resulting from the substitution of alkalis for Ca could readily account for the acceleration of the initial hydration of C3S.
