Carpet waste fibers for concrete and soil reinforcement
The study on concrete reinforcement with recycled carpet waste fibers at Georgia Tech started in 1992, funded by the National Textile Center through a grant from the U.S. Department of Commerce. In the study, carpet trims were shredded into short fibers (about 20 mm in maximum length). Concrete properties including workability, compressive strength, flexural strength and flexural toughness were evaluated for different fiber dosage levels, and comparisons were made with concrete containing virgin polypropylene fibers. Significant toughness increase was observed for both the virgin and recycled fibers. Equivalent concrete toughness provided by virgin polypropylene at certain dosage level could also be achieved by using the recycled fibers at a higher fiber dosage level. Another promising use of carpet waste is in soil reinforcement. Nature provides ample examples demonstrating the benefits of using fibers in soils, such as slope stabilization with plant roots in soil, and animal habitats from soil reinforced with sticks and fibers. It is also a practice dating back to ancient times when straws were added to clay for building construction. Fibers specifically engineered for soil reinforcement are available now (for example Fibergrids by Synthetic Industries) and have been successfully used in many construction projects in the U.S. Currently, Georgia Department of Transportation and Georgia Tech alog with industry partners and government agencies are in the process to establish a joint research program on Utilization of Carpet Waste for Soil Reinforcement in Road Construction. It aims at improving the durability and performance of road; at decreasing the cost for road construction as less soil and chemical stabilizers are needed; and at reducing the environmental impact due to road construction as less land is needed.
