Micro Silica Sand: Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica. Applications : Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste. Advantages : Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.

For example, zircon sand from Australia generally has a higher percentage of zirconium oxide than zircon sand from India. The composition of the zircon sand is crucial because it determines the characteristics of the zircon that can be formed from the metal. For example, zirconium copper with a high percentage of zirconium oxide will produce zircon with a high melting point and high corrosion resistance. The composition of the zircon sand is also essential in determining the extraction method of zircon from the ore for example, hafnium oxide-rich zircon copper is mined using hydrofluoric acid leaching. In general, the composition of zircon sand is an essential factor that affects the characteristics of zircon that can be produced from the ore and the methods that can be used to extract zircon from the ore. Zircon ore composition varies slightly based on the source and what region of Nigeria it is collected. We encourage buyers to ask for a free sample for their composition analysis and evaluation of ready-to-ship material. Samples are free, but buyers should arrange to pick up a free piece with a courier service.

Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills. It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color. Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating. From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list In particular the mill scale can be classified as follows: Einecs (european commission no.): 266-007-8 Waste code: 10 02 10 Basel code: b 12 30 Hs code: 2619.00
