steel tracks
Posted by walter on June 25, 2006
I own track vehicles and just poured a very expensive concrete slab. My track vehicles are clipping the surface, what can i do to stop this ? I’m getting ready to pour an additional section, is there anything I can do to prevent this ? I’m using 650 flex and 4000 PSI in different areas.
Putting a heavy track vehicle on concrete is probable expecting more from the concrete than it is capable of delivering, even a high quality 4000 PSI concrete.
Diamonds are the hardest substance in the world but if you hit a diamond with a hammer it will shatter. The same thing is happening with the concrete under the point load of a track vehicle. The aggregate as well as the cement paste is being shattered.
Concrete is hard but it is also brittle. What is needed is something that can absorb the impact and transfer the load to the concrete. A ductile and malleable surface treatment such as a metallic aggregate floor hardener would help. A surface treatment that can be compressed instead of being brittle would help protect the base concrete.
