Model of ion transport in alkali-activated materials
Hlaváček P., Šmilauer V.
pages 41 - +5p., full text

The paper deals with simulation of N a+ leaching process occurring in alkali activated fly ashes (AAFA). The motivation arose from the concern of efflorescence, occurring in a moisture-gradient environment in these materials. The objective aims at quantification of unknown diffusion coefficient for N a+ and estimation of time-dependent leaching process. Numerical model formulated for 1D and 3D is used to solve the balance equation. The 1D model was created in Matlab/Octave environment and the 3D model was implemented into in-house OOFEM package. The simulation shows feasibility of proposed models and a good correspondence with experimental data.
