Both silica fume and fly ash have pros and cons. Me personally I prefer silica fume because with the right regulation on the superplastisizer dosage results in SCCs with better consistency, less

Silica sol är en kolloidal lösning av När vi byggde Eskilstuna Bildemontering byggde vi nytt, från utsättning till nyckelöverlämning. Hallen är 1500 kvadratmeter stor och består av en stålkonstruktion av HSCLT Gustafsson · 2018 — added constituents such as GGBS, fly ash, silica fume, or limestone. aluminum and silicon containing minerals, usually in the form of clay. Hardened cement paste consists of hydrated and unhydrated cement , fly ash , condensed silica fume , water and organic admixtures . Admixtures are used for 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 is a byproduct of producing silicon metal or ferrosilicon alloys.

High early compressive strength High flexural strength and modulus of elasticity High bond strength Fumed silica, 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.

Once a nuisance waste product, silica fume is now a valuable addition to cement, creating concrete that is high strength, such as that used to build 311 South Wacker Drive, Chicago, once the world’s tallest reinforced-concrete building.

By using silica fume along with super plasticizers. EX:-Silica Fume used in Viaduc de Tulle Bridge, France.

Silica Fume is an extremely fine material, with an average diameter 100x finer than cement (Fig 3). At a typical dosage of 8% by weight of cement, approximately 100,000 particles for each grain of cement will fill the water spaces in fresh concrete (Fig 4).

the color of silica fume ranges from light to dark grey.

Further, it is a very fine material having around 1/50 the size of ordinary Portland cement. The average size of a particle varies 0.1-0.3 microns and the minimum specific surface areas are around 15000m2/kg. Manufacturer of Silica Fume, Cement Grout & Cement Additives offered by Guru Infrachem (Guru Corporation) from Ahmedabad, Gujarat, India Guru Infrachem (Guru Corporation) Both silica fume and fly ash have pros and cons. Me personally I prefer silica fume because with the right regulation on the superplastisizer dosage results in SCCs with better consistency, less Silica fume specific gravity is 2.2, which is somewhat lighter than Portland cement, which includes a particular gravity of 3.15.
