Product Description

Silica Fume

Refmat Corporation is amongst some of the most trusted manufacturers, suppliers & exporters of Silica Fume, that is prepared from high-grade quartz, coal, and wood chips, besides fine chemical composition. The company is committed to maintaining quality of Silica Fume in accordance with the standards determined by international bodies like ASTM as well as conducting analysis of chemical composition moisture content density, strength and reactivity. Widely known as micro silica, our range of silica fume mainly has high amorphous silicon dioxide content. These minerals are processed as per all the set industry norms and standards. Available at competitive prices, our range of Silica Fume is beneficial for concrete, and used in construction industry for its optimum purity, chemical and physical properties. Concrete including silica fume can be very durable, and can have excellent strength and is economic material for construction of bridges and other establishments. It ensures good properties like bond strength, compressive strength, abrasion resistance, etc. 

Properties & Benefits:

  • Assuring of optimum bond and compressive strengths
  • Usage of Silica Fume in concrete mixtures for lowering down permeability and resistance to chloride
  • Analyzing varied properties including chemical, mechanical and physical  
  • Manufacturing conforming to health standards and environment norms
  • Preferred to improve the fiber–matrix interfacial characteristics
  • Low permeability and great electrical resistivity
  • Utmost fineness and high silica content making it desirable refractory material
  • Reactive pozzolanic material and corrosion resistivity properties

Application:

  • High performance concrete
  • Concrete tile / panels
  • Cementitous reparation products
  • Refactory & ceramics
  • Concrete roofing, etc.
