This paper presents a review of recently acquired knowledge of the physico-chemical properties of mineral dust from Africa and Asia based on data and discussion during the Third International Dust Wor...
The effects of palygorskite on chemical and physico-chemical properties of soils: a review
Palygorskite Soil-physical-chemistry Irrigated-agriculture Rheology Flocculation Clay-migration Disaggregation Dispersion
2011/11/4
Very little was known about how palygorskite affects soil properties when it constitutes a significant component of the soil clay fraction. This constituted a serious impediment for the proper managem...
Physico-Chemical Properties of Illite Suspensions after Cycles of Freezing and Thawing
Illite-Type Clays Plasticity Pretreatment With Cold Thermal Analysis Thixotropy Viscosity
2011/12/7
Abstract: The effect of freezing and thawing on the rheological behavior of illite suspensions was studied by examining viscosity and plasticity. Stability of suspensions was characterized by a hyster...
