Application of Brown Corundum in Paving
Brown corundum is mainly used as a wear-resistant functional filler in the field of paving. Its high hardness, wear resistance and chemical stability can significantly improve the durability and damage resistance of the road surface. The specific applications are as follows:
1. Main application scenarios
Highways and airport runways
Brown corundum is added to asphalt or concrete as a wear-resistant aggregate to enhance the compressive strength and rutting resistance of the road surface.
Applicable to high-load traffic areas such as runways and docks to reduce wear and deformation.
Industrial floor and parking lot
Add to the surface of epoxy resin or concrete to improve the wear resistance and impact resistance of the floor.
Extend the service life of high-frequency use areas such as parking lots.
Sports venues
Used in sports venues such as runways and stadiums, it provides high friction and uniform particle distribution to enhance anti-slip properties.
2. Core advantages
Brown corundum has excellent wear resistance: high hardness (Mohs hardness 9.0), effectively resisting vehicle rolling and mechanical wear.
Strong stability: High temperature resistance, corrosion resistance, not easy to powder or crack after long-term use.
Environmental protection and safety: No free silica, less construction dust, in line with environmental protection requirements.
Convenient construction: Good fluidity, easy to mix with asphalt/concrete, ensuring uniform and dense road surface.
3. Normal sizes
0-1mm 1-3mm 3-5mm 3-6mm 5-8mm 8#(2.36-2.8mm) 10#(2.0-2.36mm) 12#(1.7-2.0mm) 14#(0.4-1.7mm) 16#(1.18-1.4mm) 20#(1.0-1.18mm) etc.
4. Technical extension
Some projects use it for the wear-resistant layer of the permeable road surface or the special anti-slip coating to further expand the application scenarios .
In summary, brown corundum has become an ideal material for high-load transportation facilities by improving the physical properties and durability of the road surface, especially for places that need to withstand heavy pressure and wear for a long time.
