microsilica; silica fume

Description

Micro-silica fume (scientific name "silica fume, " Microsilica or Silica Fume), in the smelting of ferrosilicon and industrial silicon, silicon through the flue gas emitted by steam oxidation, the specially designed filter collected the amorphous powder like silica (SiO 2). Micro-silica fume average 0.**0.*5 ï¿&frac*2;ï¿&frac*2; m in diameter, the size of several cement average 1.0%. Surface area for the ****7 m 2 / g, with strong surface activity. I am in compliance with the micro-silica fume SiO 2 content indicators, will be divided into products: *5% - *5% range several specifications, its physical properties and chemical composition as follows: [Micro-silica fume Specifications: ï¿&frac*2;ï¿&frac*2; products into encryption and encryption. ï¿&frac*2;ï¿&frac*2; packaging: micro-silica fume per bag of *5 kg (according to user requirements packaging) encryption micro-silica fume according to the actual production weight of delivery. ï¿&frac*2;ï¿&frac*2; Method of Use: concrete project, in accordance with the functions defined, general recommendations for the incorporation of cementing material of 5% - *0%, and reducing agent used in conjunction with. Micro-silica fume and cement, aggregate and join agitation, in strict accordance with the norms construction at the same time the need to strengthen conservation. [Storage and transport - ï¿&frac*2;ï¿&frac*2; micro-silica fume plastic bags sealed packaging, storage and transportation process, the attention of waterproof, moisture-proof.
