Anti-slip Construction material Black Fused Alumina 0.4-1mm for Wear-resisting Pavment
1. Product Description of Black Fused Alumina
Black fused alumina also belongs to the electric corundum group,it is made by high iron bauxite,high
alumina bauxite and iron oxide as main raw materials,then smelted in the electric arc furnace completely,
then made into different grit size after different processes of cooling,crushing,screening etc.
It has the characteristics of moderate hardness,good self-sharpness,strong cutting force,not easy to
burn the treatment surface.
In addition,its price is 40 percent cheaper than the one of brown fused alumina, so it could partically
replace brown fused alumina in many applications.

3. Why Black Fused Alumina is used as wear resisting pavement?
Firstly,Black fused alumina has the good wear-resistant and anti-slip performance.
Secondly,Black Fused Alumina also has the uniform and matte black color,which is especially for paving
the bridge,highway and floors.
Thirdly,Black fused alumina is 40 percent cheaper than the one of brown fused alumina,so it has the higher
price against performance ratio compared white the traditional aggregates such as brown fused alumina,
black silicon carbide.
Fourthly,That application for wear-resistant pavement has been used for nearly 10 years in Europe,Hongkong
and some developed regions in domestic.
In addition,Black fused alumina is also used in the following applications of
Bonded abrasives:Resin cutting discs;
Polishing stainless steel tableware;
Coated abrasives: sandpaper,sandbelts and flap wheels;
Sandblasting media for surface decontamination,pipeline cleaning,hull-rust and Jean cloth
sandblasting;
Polishing wax;
Refractory materials.
4. How to use Black Fused Alumina in wear-resisting pavement?
Maybe you are wondering how to use black fused alumina in wear-resisting pavement, here just
introduce one simple uasage:
To pave one or more layers of black fused alumina section sand on the cement roadbed using the resin bond,
hereby black fused alumina is used as the surface aggregates.
While the overseas countries use the asphalt as a binder.
It is only a simple method for your reference,people are able to find the right method according to the actual
demands.
