ASTM C 1240 silica fume for ultra high performance concrete

Product Overview

Description

Microsilica, 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 primarily of amorphous(non-crystalline) silicon dioxide (SiO2), its average granule diameter is 0.15~0.20um, specific surface area is 15000~20000m2/kg, and it has extremely strong surface active.

Company information

Quanzhou Winitoor Industries Co.,Ltd has been in microsilica/silica fume/micro silica since 2004 and exports thousand tons of microsilica/silica fume/micro silica to gulf countries including Qatar,

UAE,Bahrain,Oman,Korea,Japan,Canada,Vietnam,Colombia and so on.

 

There are mainly two kinds of microsilica/silica fume/micro silica,densified and undensified.

Densified microsilica:80% SiO2 to 94% SiO2

Undensified microsilica:92% SiO2 to 96% SiO2.

White silica fume:85% SiO2-96% SiO2.
