SF-250 Silica fume gel

SF-250 Silica fume gel is produced using the new generation of poly-carboxylate-based super-plasticizer, which has a higher plasticizing ability than SF-1 Silica fume gel, and results in higher compressive strengths.

SF-250 Silica fume gel is the most suitable admixture to produce self-compacting concretes with very high mechanical and chemical strengths and to provide higher efficiency and slump and especially to make extremely durable concretes.

SF-250 Silica fume gel is produced and offered according to ASTM C494 and C1202.

  • Concreting in places with densely spaced rebars, making high strength, impermeable and durable concrete against aggressive chemical agents for docs and concrete structures in the corrosive environments of Iran’s northern and southern regions.
  • Enhancing concrete’s plasticity to make self-compacted concrete
  • Enhancing chemical and mechanical strengths and impermeability of concrete
  • Economical and cost-effective
  • Straightforward and easy handling, storage and use
  • Protecting the safety and health of staff and workplace
  • Add it as 7 to 10 weight percent of the used cement during making concrete or to the truck mixer and mix for some minutes. Adding it in several steps enhances its performance.
  • This material is not classified as hazardous and harmful to health and the environment; however, it must not be swallowed or be in contact with the eyes.
  • In case of accidental contact with skin or eyes, immediately rinse it with plenty of water.In case of being swallowed, immediately visit a physician.
  • This material is not inflammable.
  • Use the contents of the container immediately after its opening, and strictly avoid using the dried material.
