Product Description
Product Description
Silica fume, also known as condensed silica fume or microsilica, is a spherical sub-micron amorphous silicon dioxide used in many applications.
Silica fume is a co-product of silicon or ferrosilicon production, consisting of ultrafine (sub-micron), amorphous, non-porous, perfectly spherical silicon dioxide (SiO2) particles, with purity levels of 85 to 99 %.
The main effect of these ultra-fine particles is to greatly improve particle packing and produce a highly pozzolanic reaction in concrete and other cementitious bond systems where the silicon dioxide reacts with calcium hydroxide, heightening performance levels and the strength and durability of these materials.
Additionally, silica fume, because of its amorphous (non-crystalline) structure and its specific area, provides other useful features to various applications, including improved sintering capabilities and enhanced high temperature performance of refractory castables, resulting in reactions between microsilica and other components of the refractory mix.
To summarize, silica fume has two key features which alone or in combination are the basis for its high performance:
- The nano-sized spherical non-porous particles create an efficient "filler effect"
- Primary particles have an average diameter of about 0.15 μm (150 nanometers)
- Microsilica is a highly reactive form of silica producing a "chemical effect"
- Thanks to its amorphous nature and high specific surface area.
For construction:
940 silica fume
, a dry silica fume powder that improves the properties and characteristics of high-performance concrete and specialist mortar formulations, acting physically to optimize particle packing and chemically as a highly reactive pozzolan. It is available in undensified (U) and densified (D) forms.
920 silica fume
, a dry silica fume powder that serves as a key ingredient in a wide range of construction materials, acting physically as a filler and chemically as a highly reactive pozzolan. It is used in fiber cement applications as a process aid, to improve ingredient dispersion and to increase hardening and overall durability. It is available in undensified (U) and densified (D) forms.
For refractory materials:
- Improved strength and service life in high-temperature applications
- Compatible with the making of complex structures, such as castables and shaped parts, thanks to good placement characteristics and low porosity, combined with excellent heat resistance properties.
