Gansu Sanyuan Silicon Materials Co Ltd

LANZHOU, China

In accordance with the iso9001: 2015 management system, sanyuan established strict rules of the production process to keep up with the world market.we can produce microsilica as various specification, sio₂content 85%~97%. Our products are exported to south america, japan, korea, germany, uae, singapore, saudi arabia, more than twenty countries and regions. Sanyuan microsilica has been used in the large domestic key projects such as: qinghai-tibet railway, beijing-shanghai railway, zheng western railway, harbin-dalian railway, wuhan railway and other railway projects and the three gorges project, south-to-north water diversion project and many other large hydropower projects.

• MOQ 25 Metric Ton

1. making high-grade concrete, can improve evidently the strength of concrete and the property of pumpage. 2. making high crack-resistance, self-waterproofing concrete, be used in the subway, tunnel and basement of high-rise structures. 3. used in maritime works and chemical industry. Due to the high densification propert, it can prevent effectively sulfate and chlorine ion from corrode, so that can extend the self-life of concrete. 4. effects on high-early strength concrete and strong concrete. 5. in project item for water conservancy and bridge, the concrete not only needs basic quota mentioned above, but also its wear-resistant quality and abrasion resistance. Thus, adding silica fume is necessary. 6. effects on high and strong spray concrete for support in tunnel, subway, and large-scale foundation ditch. 7. used in the construction item under water, such as pier, huge dam and drilling platform. 8. used in road surface concrete of expressway and large-scale bridge.

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. Silica fume 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 primarily of amorphous(non-crystalline) silicon dioxide(sio2), its average granule diameter is 0.15~0.20um, specific surface area is 15000~20000m2kg, and it has extremely strong surface active.
