Norchem Concrete Products Silica Fume is a very fine pozzolanic material, composed of amorphous silica produced by electric arc furnaces as a byproduct of the production of elemental silicon or ferro silicon alloys. When added to precast and ready-mixed concrete, silica fume produces high-performance, high-strength concrete with an increased life-span and improved structural economics. SILICA FUME is produced in conformance with the ASTM C-1240 specifications. The quality is controlled and monitored throughout the entire production process to ensure that it meets or exceeds specification requirements.

SILLITIN Z 86 puriss has a fine particle size distribution and good color neutrality.

Extendospheres® HD is our most versatile, general purpose hollow sphere grade. HD replaces heavier, more expensive components on an equivalent volume basis. Sphere One’s Extendospheres® are low density, high strength hollow ceramic spheres. They can allow the formulator to reduce the weight and overall cost of their finished goods.

MicroTalc® SR is a magnesium silicate mineral with a monoclinic crystal structure. It is characterized by its softness and platy or lamellar physical structure. When ground into a fine powder, this lamellar property gives a smooth, soapy feel.

AKTIFIT AM is a SILFIT Z 91 coated with amino functional silane.

SIKRON® is for industrial use, mighty, workable silica sand deposits are of decisive importance. Nevertheless, chemical purity and constancy are not enough in order to apply silica directly as a raw material. In Quarzwerke plants silica sands are thoroughly prepared. The raw material has to pass exten-sive cleaning-, classification-, drying- and iron-free grinding processes in order to produce silica sands, flours and powders. For the production of silica flours and -powders with a defined grain size distribution separation processes are required in addition to iron-free grinding. Quarzwerke are able to produce silica powders with grain sizes down to 1 μm due to a fine-tuned combination of grind- and classification technology. Another refining step is the surface-treatment with silanes or silan-based substances which can be adjusted to the respective application.
