Product Description
►Product Introduction:
95% Silica Fume Undensified Powder is a micro-silica fume with 95% SiO₂ content, and the Bulk density is 380-400kg/m³.
undensified silica fume, which is made from a large amount of highly volatile silicon monoxide gas produced during the smelting process, is rapidly oxidized with air and condensed into silica dust.
Silica Fume 95% Undensified Powder is mostly used in PHC pipe piles. The pre-tensioned prestressed concrete pipe columns made by centrifugal molding process have a concrete strength of C80 and above.
To ensure the quality of our Undensified Silica Fume Powder,we meets the requirement of ISO9001/14001/45001, CNAS and IAF.

►Application :
♦ Ewende Microsilica fume powder concrete has high strength, good adhesion and cohesion properties and can increase the molding thickness, its strength level can be achieved 100MPa, micro-silica powder concrete can improve its impermeability, corrosion resistance and impact resistance, can be applied to large span bridges.
♦ Ewende Microsilica fume powder concrete used in highway and railway can improve the early strength and wear resistance of concrete to a greater extent, and can advance the opening time in the maintenance and emergency repair of pavement.
♦ Ewende Microsilica fume powder can used in water conservancy and hydropower projects, concrete mixed with micro-silica powder can significantly improve the strength of the concrete matrix cement stone, while substantially improving the bonding strength between cement stone and aggregate, thus improving the seepage resistance, anti-abrasion and anti-erosion properties and extending the service life.
♦ Ewende Microsilica fume powder added to low density cement slurry has low density and small water consumption; high strength at low temperature, adjustable thickening time with low filter vector, good rheology, which can meet the requirements of construction process; high temperature resistance, which improves the thermal stability of oil well cement and prolongs the life of oil wells.
♦ Ewende Microsilica fume powder has excellent properties such as high refractoriness, and is widely used in the refractory industry, mainly for the preparation of high-temperature ceramics, ladle material, high-temperature wear-resistant materials, breathable bricks, refractory castables, etc. Refractory materials mixed with micro-silica dust can improve bulk density, reduce porosity to increase strength, improve refractory temperature and extend the life of products.
♦ The addition of Ewende Microsilica fume powder in clear concrete can greatly improve the surface quality of concrete. Micro-silica powder can effectively improve the performance of concrete mixes, but also reduce the appearance of concrete bubbles, improve the surface strength of concrete, make the surface of concrete smooth, inhibit the carbonation of concrete, resist the erosion of external harmful substances, thereby improving the durability of concrete.
♦ Ewende Microsilica fume powder concrete used in aircraft runway, can greatly improve the early strength and wear resistance of concrete, in the maintenance and repair of road surface, can advance the opening time.
♦ Harbour project concrete mixed with Ewende Microsilica fume powder, can improve the impact abrasion resistance of concrete, seepage resistance, to prevent electrochemical corrosion of reinforcing steel, and extend the service life.
