Reducing friction coeff of concrete

[graduatequestions]

Anybody got any suggestions on suitable coatings/paints for contact between two concrete surface? The codes seem to indicate you have to take a coeff of between 0.5 and 1 (when its beneficial) - i need to reduce that somewhere below 0.3, which is prob the max i can get away with.

Theres a fairly sizeable load on the concrete so the coating (or similiar) needs to be fairly hardy

You need to give more details. How long, how often, how far?

And what is the expected stress on the coating (load per unit area)?

 

[graduatequestions]

Its a one off 300mm movement taking place slowly (years rather than days) & the load on the surface is 130kPa. It only moves one way & like i said it only happens once.

I think I'm using a sliding bearing now, but I'm still interested in what is alternatives there are, maybe some sort of bituminous paint...? I'm not really sure, not my area of expertise!
