Re: Friction coefficient

[Subject Prev][Subject Next][Thread Prev][Thread Next]

If you are looking at a typical non-shrink pre-packaged cementitious grout then the roughness will likely be nearly the same as concrete for design purposes.  The other thing to note is that these types of grout have a tremendous bond with the concrete that may also need to be considered.

If you still have doubts then I would recommend calling SIKA, Master Builders, or Grace Chemicals who are all big suppliers of grout.

Cementitious grout has a very smooth sandy surface which reflect a mix made with very fine aggregates. Does anybody has a hard reference or a testing results which have explicit values friction coefficient between concrete and grout? ACI XXX chapter 11 has values concrete to concrete. But grout and concrete has different material matrix and roughness surface.
