Where can I find the friction coefficient?
Where can I find the friction coefficient?
(OP)
Hi all,
I 'm dealing with the friction between concrete and concrete, where can I find the friction coefficient? Have anybody known?
Thanks

RE: Where can I find the friction coefficient?
If one block of concrete is cast against another, even if it is smooth, there will be some keying between the surfaces that will produce a high friction.
However, after any movement between the surfaces, there will probably be grains of sand rubbed off between the surfaces. These will tend to act like ball bearings, unless the pressure is enough to crush them, and then your friction will be only a fraction of what it was without the sand or dirt between.

Single action static coefficient of friction can be easily determined by a simple test. See ASTM C 1028 and vary it to match the materials you want.
