93% Microsilica Silica Fume, also known as micro silica is silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy productionThe main field of application is as pozzolanic material for high performance concrete.
Application
Because of its extreme fineness and high silica content, silica fume is a very effective pozzolanic material. Standard specifications for silica fume used in cementitious mixtures are ASTM C1240, EN 13263.
Silica fume is added to 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.

Addition of silica fume 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.
Effects of silica fume on different properties of fresh and hardened concrete include
a) Workability: With the addition of silica fume, the slump loss with time is directly proportional to increase in the silica fume content due to the introduction of large surface area in the concrete mix by its addition. Although the slump decreases, the mix remains highly cohesive.
b) Segregation and bleeding: Silica fume reduces bleeding significantly because the free water is consumed in wetting of the large surface area of the silica fume and hence the free water left in the mix for bleeding also decreases. Silica fume also blocks the pores in the fresh concrete so water within the concrete is not allowed to come to the surface.
Application Areas:
High-performance concrete
High-strength, low-permeability concrete
Industrial flooring
Water tanks and sumps
Chemical storage tanks
Basements and sewerage pipelines
Refractory mixes etc.
Petroleum Referineries
Tunnels

Micro Silica Powder that we offer is well processed and therefore, is the perfect option on which buyers can easily rely. We are named among the renowned Manufacturers, Exporters and Suppliers of Micro Silica Powder. It is formulated under the strict vigilance of experts so as to ensure its accurate composition. One can place retail as well as bulk orders for Micro Silica Powder with us.
Description : Silica fume consists of very fine particles. Because of its extreme fineness and high silica content, silica fume is a highly effective pozzolanic material. Being a highly reactive pozzolan, silica fume chemically reacts with the calcium hydroxide present in the cement paste, creating a stronger calcium silica hydrate 'making it sticky'. The result is improved paste to aggregate bond (excellent for shotcrete) and higher concrete strengths. Silica Fume is typically grey in colour and is categorised as a supplementary cementitious material (SCM). Silica Fume is compliant to AS/NZ 3582.3:2002 and is described as a Densified Amorphous Fumed Silica.
Typical Uses : Silica Fume can be used to produce all grades of concretes. The chemical and physical properties of Silica Fume can greatly enhance the strength performance and the bonding properties of concrete. Silica Fume can be used in various applications and projects: Commercial, Civil, Mining and Marine projects. Silica Fume is suitable for inclusion in general concrete mix designs and in particular has application in high strength/ performance concretes and shotcrete / spray mixes.
Features : The addition of Silica Fume can provide;
Increase compressive strength
Reduces chloride ion permeability
Increase abrasion resistance
Enhanced sulphate resistance
Improved durability
Enhanced resistance to chemical attack and deterioration
Increase bond strength
Keeping the diverse requirements of customers, we are providing filter silica sand.
Filter media is the portion of the filter bed that removes particulate matter from the water during the filtration process. Anthracite, silica sand and high-density sand. Properties of granular activated carbon when used as a filter media.
Sand or anthracite filter media used in a wide range of bed depths and particle sizes have produced satisfactory results. Selection of the bed depth or particle size to be use in any particular filter is the responsibility of the designer and should be done with careful consideration of raw water conditions and plant pretreatment facilities. In general, for a given pretreatment of raw water and at a given filtration rate, coarse media will permit longer filter runs between washings than fine media. With good pretreatment facilities and close technical control, coarse media will yield water of satisfactory quality. With all other conditions fixed, removal of particulate matter is a function of both media size and filter bed depth, and removal generally improves with greater filter depth or with smaller media size, or both.
Our affluent industrial knowledge helps us in presenting an extensive series of Filter Media Sand. Our products can also be customized as per necessities of our patrons.

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.
Silica Sand * Silica Sand is a type of sand usually available in the form of quartz. It is a hard and crystalline form of mineral components. * Silica sand is the most abundant mineral with the purity more than 99.0%. It is the preferred choice of consumption for various industrial purposes.

Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications. Silica sand is used in industrial processing, to make glass, as fill, and to create molds and castings.
Silica sand is produced by crushing sand stone or quartzite of open texture, and washing and garding it to yield requisite grain distribution. Silica flour is produced by crushing grinding and washing the high grade quartz, quartzite rocks or from white silica sand.
Salient Features
Silica Sandstone is moisture free, fritable & hard.
Grain size of the particles is variable.
Friable & mainly brown to grey in colour.
Silica Sand is a naturally occurring granular material composed primarily of Silicon Dioxide (SiO). It is one of the most important industrial minerals and is widely used in glass manufacturing, foundries, construction, ceramics, water filtration, chemicals, and oil & gas industries. High-purity silica sand is valued for its chemical inertness, hardness, high melting point, and uniform grain size.
