KVPozz-MS Silica Fume, is an organic & amorphous pozzolanic silica which is being used in the production of various high performance, high strength a low permeability concrete mixes.We prepare it by using suitable grinding methods and milled it to less than 45 microns to achieve higher-specific surface area for better reactivity in concrete mix application.
Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) 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 nm.

Silica fume particles have an average diameter of less than 1 micron. Silica fume is a grey superfine powder with a density of 2.2g/cm³. Generally divided into densified silica fume and undensified silica fume, the bulk density of undensified silica fume is 200-350kg /m³, the bulk density of densified silica fume is 480-720kg /m³.
The material consists of amorphous, spherical particles with bulk density of 600-650 kg/m3, and in the form of un densified Silica Fume. Through a process we will increase the bulk density of the undensified Silica fume and the material is then produced as densified Micro Silica (Silica Fume).
Zirconia silica fume is a compound of zirconium dioxide, zirconium oxide melting products. The production of silicon-zirconium off special device which used to collect the silica powder, not only has the general characteristics of sillca, but also a certain amount of zirconia powder.
Abstract— This research describes the importance of the effect of silica fume on concrete properties and the advantages of its use in the Kurdistan region, Silica fume can either be 'addition' (added separately at the concrete mixer) or incorporated into a factory-produced composite cement.

Silica fume shall be stored in such a manner as to permit easy access for the proper inspection and identification of each shipment. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Densified Silica Fume, also called silica fume or micro silica, is a byproduct of production silicon metal or ferrosilicon alloys. Silicon metal and alloys are produced in electric furnaces.The raw materials are quartz,coal and woodchips.The smoke that results from furnace operation is collected and sold as silica fume, silica fume consists
CHARACTERISTICS OF SILICA FUME 1. Physical Properties Diameter is about 0.1 micron to 0.2 micron Surface area about 30,000 m²/kg Density varies from 150 to 700 kg/m³ When its density is about 550 kg/m³ it is the best suited as concrete additive 2. Chemical Composition Contains more than 90 percent silicon dioxide Other constituents are [.]
Condensed silica fume is essentially silicon-dioxide (more than 90%) in non-crystalline form. Since it is an air borne material line fly ash it has spherical shape. It is extremely fine with a particle size less than 0.1 micron and specific surface area of about 20,000m²/kg. Silica fume is used as an artificial pozzolanic admixture in concrete.
2 SCOPE Silica fume up to 10 as part replacement (by weight of cementitious materials) is suggested to be used in concrete as per IRC: 15 for rigid pavement. Pavement Quality Concrete (PQC) with the use of silica fume shall have minimum flexural strength of 4.5 MPa and the corresponding compressive strength of 40 MPa.

using silica fume on the properties of fresh and hardened concrete made with crushed bricks through experimental investigation. The effect of using silica fume on the workability of concrete due to addition of silica fume was measured by taking the slump of the concrete produced with and without silica fume.
Concrete containing silica fume can have very high strength and can be very durable. Microsilica (Silica Fume) is a mineral composed of ultrafine amorphous spheres of silicon dioxide (SiO2), produced during the manufacture of silicon or ferrosilicon. The average particle is 0.15-0.20 micron in diameter.
