EGYPTIAN SILICA SAND What is Silica?
Silica most commonly exists in the form of quartz - the second most common mineral on the earths surface. It is hard, chemically inert and has a high melting point. These are prized qualities for many industrial applications. Silica for industry is supplied in the form of sand, which closely resembles that found on the beaches of our coastline. Silica sand is an essential raw material that contributes so much to modern society. Wherever you go, youre always close to products made from silica sand. Without silica sand, there would be no glass, no ceramics (tableware, sanitary ware), no houses, no hospitals, no schools, no roads, cars or trains, no computers or televisions We could not even return to the Stone Age, because silica is abundant in rocks!
Silica sand is a raw material that is used in tyre production to make tyres last longer and improve their performance Silica sand is used in football pitches and golf courses. Root zone sands ensure good drainage and stability while top dressings and sports turf sands improve the quality and durability of the playing surface

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 �¼m (150 nanometers)
Microsilica is a highly reactive form of silica producing a "chemical effect"
Thanks to its amorphous nature and high specific surface area.
