Cycloolefin copolymer/fumed silica nanocomposites
Journal of Applied Polymer Science, 2010AbstractWe prepared cycloolefin copolymer (COC)/fumed silica nanocomposites by melt compounding to study the effect of the filler dimensions (filler surface area) on the physical properties, with particular attention to their thermal, mechanical, and optical behaviors.

Polydimethylsiloxane at the interfaces of fumed silica and zirconia/fumed silica
Applied Surface Science, 2007Abstract Polydimethylsiloxane (PDMS)/fumed silica A-300 and PDMS/ZrO2/A-300 were studied using adsorption, thermogravimetry, temperature-programmed desorption (TPD) mass-spectrometry, infrared spectroscopy, XRD, and broadband dielectric relaxation spectroscopy. ZrO2 was synthesized on fumed silica with zirconium acetylacetonate in CCl4 at 350 K for 1

Wet-Mix silica Fume Shotcrete: Effect of Silica Fume Form
"SP-132: Fly Ash, Silica Fume, Slag, and Natural Pozzolans and Natural Pozzolans in Concrete - Proceedings Fourth Interna", 1992This study investigated the influence of the different forms of silica fume on the plastic and hardened porperties of wet-mix shotcrete. The silica fume forms studied were: uncompacted silica fume; compacted low density silica fume; compacted high density silica fume.

Sustainable route for silica preparation from silica fume
Environmental TechnologySilica fume (SF) is a major voluminous and bulky by-product of the ferrosilicon industry, and its disposal poses a significant environmental concern. To address this issue, a sustainable approach was employed to transform SF into silica powder using a precipitation method.

Alkali silica reactivity of agglomerated silica fume
Cement and Concrete Research, 2007It is commonly accepted that replacement of a portion of cement in mortar or concrete with well-dispersed silica fume reduces expansion caused by alkali silica reaction. Recently there has been much discussion that large, agglomerated particles of silica fume may actually act as alkali silica reactive aggregates, thereby increasing expansion rather ...
