The nanostructural evolution of metakaolin-based geopolymer binders is investigated using in situ X-ray pair distribution function analysis.
Aqueous slurries consisting of 50 wt.% of TiO2 particles, 0 1.2 wt.% ammonium polyacrylate as a dispersant and up to 15 wt.% styrene ester acrylic copolymer as a binder were investigated using settling experiments.
The physical properties of these binder samples were investigated using conventional tests such as penetration, softening point and ductility while their rheological properties were investigated using Superpave binder tests such as rotational viscosity, dynamic shear rheometer and bending beam rheometer test.
Low temperature properties of the styrene-butadiene-styrene (SBS) modified asphalt binder and aged SBS modified asphalt binder containing rejuvenators were investigated using conventional methods (penetration and ductility at 5 °C), Fraass breaking point test, dynamic shear rheometer (DSR), force ductility test and bending beam rheometer (BBR).
Twenty-four kinds of BaTiO3 slips for MLCC application were investigated using three different binder systems: one solvent-based, and two water-based with water-soluble acrylic binder and aqueous emulsion binder systems.
Six factors: binder content, steam amount, mixing time, impeller speed, spray pause time, and filler content were investigated using a two-level quarter-fraction factorial design of experiment (DOE) for each binder type.
To begin with, the effect of the nature of the monomers composing the polymeric binder, on the chemical reactivity between the binder and the intumescent additives is investigated using thermogravimetric analysis, solid state NMR and FTIR analysis.
The effect of the type and content of newly developed SBS modifiers was investigated using typical binder tests.
