Abstract
"Fiber reinforced concrete is gaining in acceptance and usage as its strength and toughness benefits are realized. Polypropylene fibers are currently the most commonly used fibers. However, the cost of virgin plastics limits the percent content that can be economically added to concrete. One would first believe that recycled plastics could offer a viable alternative to virgin-plastic fibers, but at present time extra selection and cleaning steps required to reprocess the recycled plastic into fibers makes it more expensive than virgin-plastic fibers. A fiber rolling process conceived and developed at the University of Missouri-Rolla has the potential of making recycled plastic fibers an economic alternative to virgin-plastic fibers in concrete reinforcement. This research effort has focussed [sic] on two primary issues. The first issue involved designing and fabricating a laboratory-scale rolling mill, the heart of this new process, that has confirmed the feasibility of the fiber-rolling concept. After a review of conventional flat rolling models for steel, the second issue involved developing a mathematical model of the mechanics involved with fiber rolling. The model allows predictions of roll torques and separation forces to be made for the process, which have been benchmarked against those for flat rolling processes. The model has also allowed a parametric study to be completed as the first step in eventually optimizing the process"--Abstract, page iii.
