Product Description

Microsilica, this product comprises microscopic particles collected by filters downstream from the smelting process in silicon and ferrosilicon plants. Adding it to concrete and other materials, increases their density and wear resistance, which extends the life of structures. Microsilica stands’ average diameter is between 0.1um and 0.15um. Its specific surface area is between 15M2/g and 27M2/g, which have superpower surfactivity.



Densified and undensified Silica Fume for Concrete/Cement/Refractory



Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys.It consists primarily of amorphous silicon dioxide (SiO2),its average granule diameter is 0.15~0.20 µm,specific surface area is 15000~20000 m2/kg.


2.Main Properties

     a.Very low permeability to chloride and water intrusion.

     b.Extremely high electrical resistivity.

     c.Increased abrasion resistance on floors,highways,marin structures.

     d.Superior resistance to chemical attack from chlorides,acids,sulfates.

High Performance Concrete (HPC) containing microsilica – has been identified as one of the more important advanced materials necessary in the effort to rebuild the nations infrastructure.  In addition to increased strength and enhanced durability, HPC produced with microsilica delivers increased toughness; increased resistance to abrasion, corrosion and chemicals; and placement and life-cycle cost efficiencies.

Highway bridges, parking decks, marine structures and bridge deck overlays are subject to constant deterioration caused by rebar corrosion current, abrasion and chemical attack.  Microsilica will protect concrete against deicing salts, seawater, road traffic and freeze/thaw cycles.  Rebar corrosion activity and concrete deterioration are virtually eliminated, which minimizes maintenance expense.
