ABSTRACT:
The present invention is an apparatus for introducing fibrous material into a continuous flow of concrete. Fibrous material is pushed through an aperture located in the bottom of a container. As the fiber falls from the aperture, it is agitated and spread evenly onto the mixture of concrete. The resulting distribution of fiber within the concrete mixture increases the strength of the concrete while preventing undo grouping of the fibers.
