摘要
为研究碳纳米管(CNTs)改性活性粉末混凝土(RPC)材料的水化过程,测试了不同CNTs掺量的RPC材料在不同养护龄期下的交流阻抗谱曲线,分析了RPC材料的水化过程、内部孔隙和导电能力。提出了RPC材料阻抗谱等效电路模型,给出了电路模型中具体元件参数的计算方法和计算结果,结果表明模型与实测的结果吻合。
The reactive powder concrete （RPC） reinforced by carbon nanotubes for different curing ages were measured by an AC-impedance spectroscopy to investigate the hydration process of the R.PC. The hydration, porosity and conductivity of the RPC were analyzed. The equivalent circuit model of the AC-impedance spectroscopy curves was proposed for the RPC. The method for calculating the parameters of the model was introduced, and the calculating results were discussed. It was indicated that the simulated data were similar to the experimental results.
