Abstract

A new method, computerized granulometric analysis in suspension (C-GRAINS), is suggested for the sedimentation analysis of soil particles based on the relation between the specific weight and liquid pressure of a soil suspension. Theoretical aspects concerning this new testing method are discussed, and a prototype C-GRAINS system is fabricated accordingly. The general behavior of the new system is studied, and the corresponding sedimentation results are compared to current ASTM standards.
