This paper shows that the pull-out load (or equivalent bond) associated with a randomly oriented steel fiber is not necessarily lower than that of an aligned fiber; and that the bond associated with a group of randomly oriented fibers decreases drastically when the number of fibers pulling out simultaneously from the same area increases. These results explain why the addition to a concrete matrix of fibers with highly improved bond properties does not lead to an equivalent improvement in composite properties.
