Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications. Sand is the general term for broken down granules of minerals or rocks, technically between about one-sixteenth of a millimeter to two millimeters in diameter, falling between silt and gravel in the spectrum of sizes. There are many varieties of sand in the world, each with their own unique composition and qualities.

Silica is another name for Silicon dioxide, SiO2, of which quartz is a specific latticed structure. So, silica sand is quartz that over the years, through the work of water and wind, has been broken down into tiny granules. These granules can be used for many different purposes and can be found in most non-tropical regions of the world.

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.

Fumed silica (CAS number 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler.
Fumed silica has a very strong thickening effect. Primary particle size is 550 nm. The particles are non-porous and have a surface area of 50600 m2/g. The density is 160190 kg/m3.

Silica fume, also known as microsilica, is a byproduct of the production of silicon and ferrosilicon alloys. It is an ultrafine powder consisting of spherical particles, typically about 100 times smaller than the average cement particle. This fine powder is rich in silicon dioxide (SiO) and is highly reactive when mixed with cement, making it a valuable additive in construction materials.



Features of Silica fume:
1, With good insulation: due to the high purity, low impurity content, stable performance, excellent electrical insulation performance, silica fume makes the cured product has good insulation performance and arc resistance performance.

2. It can reduce the peak exothermic temperature of the curing reaction of epoxy resin, reduce the linear expansion coefficient and shrinkage rate of the cured substance.

3, Corrosion resistance: silicon powder is not easy to react with other substances, and most of the acid, alkali can not react chemically.Its particles evenly covered on the surface of the object, with strong corrosion resistance.
