Abstract
The settling behavior of dilute clay-water mixtures is examined. At first, settling type is classified into the four based on the precise observation of settling phenomena. Two factors are considered to cause the difference in the settling type; one is the degree of flocculation which is determined by salt concentration in water and the other is the degree of particle's interaction which is determined by mixture's solid concentration. Two of the four settling types, i.e., zone settling and consolidation settling, are nextly examined from the quantitative view point. The results show that settling is strongly influenced by the total solid weight contained in a mixture.
