Fibre reinforcement for Slab on Grades
Fibre reinforcement for Slab on Grades
(OP)
We are designing loading dock slab on grade for trailer loadings. Client don't like to use welded wire fabric due to its poor quality and having past bad experiences.
We want to suggest steel fibre reinforcement in concrete. It all depends on the fibres type. How it can work, it's modulus of rupture should be definatley different and all depends on fibres.
Does anybody know it is good to use steel fibre reinforcement or epoxy coated rebars. Only problem in rebars is that lot of time is needed for placing and it might be uneconomical also.

For a loading dock for pneumatic tired truck/trailer loading, you are much better with conventional reinforcing bars. Depending on the loading and soil conditions, I sometimes use top and bottom layers. Don't know why you want epoxy coating on the bars.
Pay especial attention to the joints, because that is where most problems occur. Keyed joints are no good, as the top section of the key will sometimes shear off. Don't put dowels too close to the corners.

Since when are fibers considered "reinforcement"?
They can enhnace the properties of concrete but really do not reinforce it.
Depending whether the application has hard or soft tires on the fork lifts, the type and properties of added materials (fibers, admixtures, etc.) will vary.

Don't know about spacing the bars that far apart. Some concretors have mighty big feet! So do I, and I prefer to walk on the top mat.
