Introduction
85% Undensified Silica Fume is a micro-silica fume with 85% Conteúdo SiO2, and the Bulk density is 250-400kg/m³.
Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. It consists primarily of amorphous silicon dioxide (SiO2), its average granule diameter is 0.15~0.20 μm, specific surface area is 15000~20000 m2/kg. Mainly used for high transparency, high resistance to tear silicone rubber, silicone grease, sealed packaging materials such as capacitors.

Aplicações
- Conservação da água e engenharia hidrelétrica: nas peças anti-infiltração e anti-abrasão, depois de misturar com pó de micro-sílica, it can greatly improve the anti-seepage, anti-cracking, anti-abrasion and anti-cavitation performance.
- The production of high-strength concrete: silica powder as admixture to make high-strength concrete, the actual application of its strength level can be achieved 100Mpa.
- Seaport engineering: concrete mixed with silica powder can improve the concrete’s anti-abrasion performance, anti-seepage performance, to prevent electrochemical corrosion of reinforcing steel.
- Traffic engineering: concreto em pó de sílica usado em pavimentos de rodovias e pistas de aeronaves, pode melhorar muito a resistência inicial e a resistência ao desgaste do concreto, na manutenção e reparação de pavimentos rodoviários, você pode adiantar o horário de abertura e aumentar os benefícios econômicos.
- Concreto projetado: melhorar significativamente o desempenho de adesão e coesão do concreto plástico, reduzir significativamente a quantidade de recuperação, aumentar a espessura do concreto projetado uma vez formado, encurtar o período de construção e economizar o custo do projeto.
