摘要：
The paper presents a method of pore connectivity analysis applied to specimens of cement based composites differing in water to cement ratio. The method employed X-ray microtomography (micro-CT). Microtomography supplied digitized three-dimensional radiographs of small concrete specimens. The data derived from the radiographs were applied as an input into the application based on the algorithm called 'random walk simulation'. As the result a parameter called diffusive tortuosity was established and compared with estimated porosity of examined specimens.
