Introduction
99% Undensified Silica Fume is a micro-silica fume with 99% Conteúdo SiO2, and the Bulk density is 250-400kg/m³.
Fumaça de sílica, also called Microsilica 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.
Basic Attributes
- Very low permeability to chloride and water intrusion.
- Extremely high resistivity (20 para 100 times greater than normal concrete).
- Increased abrasion resistance of decks, floors, highways and marine structures.
- Excellent resistance to chemical attack by chlorides, acids, nitrates and sulfates.
Advantages
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.
