Scancem silica fume

How microsilica works in concrete?. Microsilica is a product of silicon metal smelting. Most particles are less than 1 micron in diameter (0.00004 inches), It’s usually 100 times thinner than normal cement, It is produced in an arc furnace of 2000 degrees Celsius and released from the liquid at the bottom of the furnace. Silica Fume will greatly increase concrete strength and reduce permeability which in turn contributes to increased durability for chemical resistance, chloride attack, sulfate attack, and abrasion resistance. Increased cohesion using Silica Fume aids in Self Consolidating Concrete and Shotcrete applications. silica.fume.

Scanfibre is supported by tried and tested… Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys.

Silica Fume will greatly increase concrete strength and reduce permeability which in turn contributes to increased durability for chemical resistance, chloride attack, sulfate attack, and abrasion resistance. Increased cohesion using Silica Fume aids in Self Consolidating Concrete and Shotcrete applications.

Fumed Silica CAS Numbers: 1) CAS No. 112945-52-5 (Specific) 2) CAS No. 7631-86-9 (General) Fumed Silica RTECS Number: VV310000 Silica Fume is a finely-divided mineral admixture, available in both uncompact and compacted forms . This ultra-fine material will better fill voids between cement particles and result in a very dense concrete with higher compressive strengths and extremely low permeability. Smaller proportions of silica fume were used because of the very high reactivity of silica fume with calcium hydroxide produced by the hydration of Portland cement .

UHPC has very superior properties that are remarkably different to the properties of Normal Strength Concrete (NSC) and High Strength Concrete/GFRC. Silica fume, also known as microsilica and nanosilica, is a highly reactive pozzolanic filler, which is used to achieve high strength and dense concrete. Silica fume is a by-product of the manufacture of silicon and ferrosilicon alloys from high-purity quartz and coal in a submerged-arc electric furnace. Silica fume, also known as microsilica, is an amorphous polymorph of silicon dioxide, silica.
