La description

Micro silica ,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.*5~0.*0um,specific surface area is ****0~****0m2/kg,and it has extremely strong surface active.

Product Description of Micro Silica Powder

Micro silica powder designed to boost the quality of concrete. It helps to increase the flexural, bonding, and compressive strength of concrete. It also acts as a Corrosion Inhibitor and enhances the life of concrete structures by reinforcing against damage from corrosive effects. Besides this, Micro silica powder also improves overall concrete quality by minimizing the risk of Alkali-Silica Reaction (ASR), more commonly known as Concrete Cancer. Micro Silica powder by Binzhou Chengli Building Materials Co.,Ltd. is a mineral admixture made from very fine sold glassy spheres made of Silicon Dioxide (SiO2). It is a fine amorphous silica whose particles are almost **0 times smaller than the average particles of fly ash and cement. Micro Silica offers greater strength to the concrete, provides better dispersion to the concrete, and improves the rheology of the concrete by reducing its water-binder ratio.
