AbstractComputer simulation is applied to reveal the microstructural influence on the impedance behaviour ofa hydrating cement paste system. Changes in two major parameters, porosity and mean pore size, have been taken into account in constructing the impedance spectrum. Simulation results show that a decrease in porosity leads to a decrease in both high-frequency resistance R1and high frequency arc diameter R2. It has no effect on phase angle shift. A change in mean pore size has a more significant influence than a change in porosity on impedance behaviour, i.e. R1 and R2 of a hydrating cement paste system. It also affects the extent of phase-angle shift.
