The carbonation is a pathology which affects cement-based materials such as concretes and mortars.The carbonated skin of material becomes brittle and losses the...

This experimental work is a contribution to the study of rheological and pipe flow proprieties of complex fluids (yield stress and thixotropic). Bentonite suspensions...

Rheology of high molecular weight polymer solutions at submicroscale is investigated, with a particular emphasis on the wall slip characterization. Our approach is to...

Starch, biopolymer of reserve, is the major component of cereals and of crop plants, has many industrial applications after hydrothermal processes. The objective of...

Two aqueous systems at 20°C in 0.1 M NaCl and pH 7.2 containing globular pea proteins and sodium alginate were investigated in this study. First, phase behavior of (i)...

Titanium alloys used for the manufacture of rotating parts of aircraft engines undergo complex thermomechanical processing schedules, involving usually several forging...

Renewable energy sources are developed worldwide due to high oil prices and to limit greenhouse gas emissions. In this context, some groups have focused their work on...

A material exhibits a thixotropic behaviour if its apparent viscosity decreases in time under stress, and if it progressively recovers its initial viscosity when the...

This paper evaluates the applicability of different shifting techniques for constructing complex modulus master curves using the time-temperature superposition...

The thermomechanical behavior of bituminous materials and the durability of the asphalt-aggregate interface are key factors to predict pavement damage. This thesis...

Polymacromonomers (PMs) are well-defined branched polymers resulting from macromonomer polymerisation. The PM investigated in this work have been prepared using...
