摘要：
A random 2-D digital-image-based microstructural model is used to simulate impedance spectroscopy of cement paste. Results of these simulations are used to interpret previous experimental results. The main features of the impedance spectra of cement paste are the result of the composite nature of cement paste; in other words, the electrical response varies as different phases, each with its own specific electrical properties, are consumed and generated. Percolation theory is invoked to help explore certain relationships between two- and three-dimensional analysis.
