Bitumen Emulsion-Mineral Surface Interactions: An NMR Study on the Interface Layer Composition. [PDF]

open access: yesMagn Reson Chem
We describe a 1H NMR approach to study the interface layer formed by a specified bitumen emulsion in the presence of non‐magnetic as well as magnetic minerals. This approach is based on the consecutive flushing off “bulky” components of the bitumen emulsion and the following extraction of the surface layer material, which can then be analyzed by NMR ...

Storage Stability of Bimodal Emulsions vs. Monomodal Emulsions

open access: yesApplied Sciences, 2017
Storage stability is a very important parameter that has to be considered in the formulation of asphalt emulsions. When monomodal emulsions are formulated, Stokes’ law is fulfilled, therefore the higher the viscosity the less sedimentation, or the lower ...

Investigation on Properties of Cement Bitumen Emulsion Mortars (CBEM) in Consideration of Emulsifier Types

open access: yesAdvances in Materials Science and Engineering, 2020
In order to investigate the influences of emulsifier types on properties of cement bitumen emulsion mortars (CBEM), anionic and cationic emulsifiers were used to prepare CBEM in this work.

Effect of steel slag aggregate and bitumen emulsion types on the performance of microsurfacing mixture

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2020
Microsurfacing has recently been accepted widely as an effective method for preventive maintenance of pavements. Microsurfacing is a mixture of cationic polymer-modified bitumen emulsion, 100% manufactured well-graded fine aggregate, mineral filler ...

Probing Mechanical Properties of Water-Crude Oil Interfaces and Colloidal Interactions of Petroleum Emulsions using Atomic Force Microscopy [PDF]

open access: yes, 2017
Atomic force microscopy (AFM) is frequently used to elucidate complex interactions in emulsion systems. However, comparing results obtained with “model” planar surfaces to curved emulsion interfaces often proves unreliable, because droplet curvature can ...

Characterising rag-forming solids [PDF]

open access: yes, 2013
In oil sands froth treatment, an undesirable intermediate layer, often accumulates during the separation of water-oil emulsions. The layer referred to as rag layer is a complex mixture of water, oil, solids and interfacially active components.
