Executive Summary This is the second annual report of the IFPRI Suspension Rheology project 1991-1994 at the K.U.Leuven (Belgium). Whereas the two previous projects at K.U.Leuven dealt with the flow properties of stable colloidal dispersions, the present one concentrates on flocculated systems. In particular it is being attempted to generate some basic information on how to manipulate the complex rheology of reversibly flocculated dispersions. This latter term refers here to colloidal systems in which floes develop at rest, which however can be broken down reversibly during flow. Such...
