摘　　要：分析研究了复合胶凝材料的合成反应机理,基于活性率法结合热动力学分析技术推导得出了其粉煤灰的反应程度计算公式,明确了各个参数的取值范围;通过实验对该公式进行了验证,并定量评价研究了复合胶凝材料的活性特征,得出了养护龄期和温度对其活性特征的影响规律。结果表明,该公式能定量研究复合胶凝材料中粉煤灰的反应程度,但有待进一步验证。The reaction mechanism of the complex cementitious materials were studied and analyzed. The for mula about hydration degree of fly ash was deduced and the range of the various parameters was conformed based on the activity rate method and the thermodynamic analysis technology. The formula was tested and verified via the ex periments, which quantitatived evaluation of the activity characteristics about the complex cementitious materials and obtained the influence laws about curing periods and temperature. The results showed that this formula can analyze the hydration degree of fly ash quantitatively in complex cementitious materials, but needs to be validated.
