Abstract

Compaction process of granules was studied by compressing a granule bed with a constant rate increase of applied stress. Compaction process at the lower range of applied stress proceeded with the decrease of intergranular void volume. The change of the intergranular porosity, ε_i was expressed as In (ε_io/ε_i) = (P/P_c) In (ε_io/ε_if) in the stress range from 0 to P_c, where P is applied stress, ε_iois the initial intergranular porosity and ε_if is the intergranular porosity at P_c •P_c was nearly proportional to the granule strength, p_gand expressed by(l-ε_if)ρ_g.
