Introduction
92% Undensified Silica Fume is a micro-silica fume with 92% Conteúdo SiO2, and the Bulk density is 250-400kg/m³.
Fumaça de sílica, also known as Micro-silica powder and cohesive silica fume, is formed when smelting ferrosilicon and silicon metal, the mineral-heated electric furnace emits extremely volatile Si gas and SiO2, and the gas is discharged and precipitated by oxidation condensation with air. Micro-silica powder is a by-product of the whole big industrial smelting and needs to be collected by environmental protection equipment. The initial density of micro-silica powder is only 150-200 kg/m3, which will cost a lot in transportation cost, and in order to reduce the transportation cost of micro-silica powder, the encrypted micro-silica powder becomes the ideal choice for most manufacturers.

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.
