The shock adiabats have been built experimentally in the range of moderate pressures for three porous materials: Al{sub 2}O{sub 3} wheat flour, and their mixture. The model, which describes the behavior of porous powder materials under large-amplitude dynamic loading, has been constructed. The model applicability to describing the shock wave processes is confirmed by good agreement of the calculated shock adiabats and the data obtained in the experiments. The compressive strength of compacted samples has been determined. The possible trend of further researches is presented in conclusion. 15 refs., 19 figs., 6 tabs
