Concrete friction coefficients
Concrete friction coefficients
(OP)
Does anyone happen to know what the static coefficient of friction for concrete on concrete is? Approximately?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Concrete friction coefficients
I have not heard about the static coefficient of friction between concrete to concrete. But know the friction coefficient bet. rubber and concrete which is 1.0.
Extending the same logic and since the concrete is heavy the static coefficient of friction may be around 1.0.

Concrete/concrete = 0.4
Concrete/plain steel = 0.1
Concrete/softwood = 0.4
Concrete/hardwood = 0.3
Concrete/granular soil = 0.4

1. between smooth concrete blocks (seperately cast)- 0.3 to 0.4
2. single casting of concrete block cracked into two parts 0.5 to 1.0.
Moreover present of moisture and presence of crushed material between the surfaces may bring down the friction factor dramatically. You have to be more specific about the conditions and then you can arrive at a more reasonable approximation.

RE: Concrete friction coefficients
Any chance you can point to a reference for the use of 0.3 to 0.4 for seperately cast concrete? We're trying to verify that concrete traffic barriers can be used as ancorage points against a lateral load.
Thanks,

Concrete/plain steel = 0.1 is too small. That is the friction of coefficient between Teflon to Teflon. We use 0.5 betw steel and conc.
