Abstract

The authors'' theory of porosity estimation from particle size distribution was modified to make allowances for the size and species dependences of packing characteristics of particles. The new version is examined together with other existing theories by using well known relations and past experimental data. It is shown that the estimates by the modified theory are almost consistently in good agreement with the known data whereas the other theories examined show theoretical deficiencies that sometimes give rise to large deviations for mixtures of particles of remarkably different sizes. Some possible problems are also discussed in association with the new assumption introduced.
