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 wood-chips.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.
1. Has good stability, the material mixed evenly, good fluidity, the initial consistency is small, with good pumpability, on-site construction of low difficulty
2. High pulp rate, cost-effective, can reduce the cost of cementing, to achieve the purpose of energy saving.
3. High compressive strength, less free liquid, can effectively reduce the water loss of cement slurry, water analysis, to meet the quality requirements of cementing
4. After mixing cement has a low specific gravity and does not cause pressure-leaking formation, it can meet the needs of various complex formation of oil and gas cementing
Prevents reinforcing steel corrosion in concrete, due to its extremely low permeability to chloride-ion intrusion and high electrical resistivity.
· Greater impermeability, barring the ingress of moisture, chemicals and other contaminants
· High early strengths, assuring increased efficiency and greater cost effectiveness in production of prestressed and precast concrete
· High ultimate compressive strengths (8,000-20,000 psi), proportionate to amount of silica fume and the water-to-cementitious ratio
· Substantially greater resistance to corrosion, abrasion and erosion, chemical attack and freeze/thaw damage.
