摘要:
采用电化学阻抗谱方法对掺入粉煤灰或矿渣的混凝土水泥水化过程进行了研究，从不同龄期混凝土电化学阻抗谱的特征出发，分析了矿物掺合料对混凝土中水泥水化过程的电化学阻抗参数的影响，讨论了混凝土结构的变化与发展．研究表明：不同粉煤灰或矿渣掺量的混凝土电化学阻抗谱具有相同的变化趋势．在水化早期，随着矿物掺合料掺量的增大，阻抗参数 、 和 减小，混凝土的总孔隙率增大，结构变疏松；水化后期，由于矿物掺合料的二次水化作用，阻抗参数 、 和 逐渐增大，混凝土的总孔隙率减小，结构变密实，且随矿物掺合料掺量的增加混凝土细观结构的密实度越高．
Abstract:
he cement hydration of concrete mixed with fly ash or slag was studied by means of the electrochemical impedance spectroscopy. Starting with the characteristics of electrochemical impedance spectrum, the influence of the mineral admixtures on electrochemical impedance parameters in the concrete cement hydration process was analyzed and the development and changes of the concrete structure was discussed. The results show the concrete electrochemical impedance spectroscopy with different quantity of fly ash or slag is the same in trend. During the earlyst age of hydration, the impedance parameters, and reduced and the total porosity of the concrete increased with the increases of the amount of mineral admixtures incorporated in concrete and the structure of concrete becomes loose. In the latest age of hydration, the impedance parameters , and gradually increase because of the secondary hydration effects and the total porosity of the concrete decreased and the structure of concrete becomes compacted, and with the increase of mineral admixture content, the meso-structures of concrete becomes more compact
