Daze has trade dealings for the distribution of “Ferrosil” & Topken Silica fume, a beneficial, super pozzolonic mineral additive for cement based materials like Cementatious Products. “Ferrosil” & Topken Silica fume originates from the production of silicon metal and Ferro- Silicon Alloys. The material consists of amorphous, spherical particles with bulk density of 200-300 kg/m3, and in the form of un densified Silica Fume. Through a process we will increase the bulk density of the undensified Silica fume and the material is then produced as densified silica fume. The country of origin of “Ferrosil” & Topken brand our silica fume is from China.

“Ferrosil” and Topken Silica fume is manufactured with stringent quality and environmental control and it meets the mandatory requirement of the international standards. The following data sheet will give you micro silica’s (Silica Fume’s) specification in different standards as well as our the “Ferrosil” & Topken Silica fume’s standard’s.

Fly Ash is a fine residue resulting from the burning of coal at high temperatures. The most common sources of Fly Ash are electric power generating stations. Fly Ash has become the predominant pozzolan in use throughout the world due to performance and economic factors. The main content of Fly Ash is silica. The Origin of our Fly Ash is from India.

There are 2 types of Fly Ash Class F and Class C. The types are differentiates based on the sum of Silicon Dioxide (SiO2) + Aluminium Oxide (AI2O3) + Iron Oxide (Fe2O3). If the sum of this is greater than or equal to 70% it is called Class F Fly ash and if the percentage is greater than or equal to 50% it is called Class C Fly Ash.

Economic Benefits: It replaces Portland cement up to 20 - 50%

GGBFS and finely ground palletized slag’s are marketed separately to the concrete producer and used as a partial replacement for Portland cement. Replacement dosages between 5% and 70% by mass of cement material are common. Fineness, glass content and mineral constituents are generally considered to be important factors regarding the cement activity of slag. We have sources of GGBS from UAE, India and China.

Effects of Slag on properties of fresh and hardened concrete

Concrete with Type IS cement or with higher dosages of GGBFS added at the mixer usually will have lower heat of hydration

Concrete containing slag may show longer time of setting than straight Portland cement mixtures particularly. for moderate and higher dosages and at lower ambient temperatures

Increasing slag dosage is associated with lower permeability in concrete

Concrete containing GGBFS dosages greater than 35% will give in improvement in the resistance to sulphate attack as well as suppression of alkali aggregate expansion
