Abstract
The goal of the proposed research is to recycle PET and eventually other plastic wastes, through depolymerization while avoiding costly purification and color-removal steps, into low-cost and highly durable rapid-setting rehabilitation materials. Successful implementation of the proposed technology will impact two critical issues of our time - infrastructure and the environment - through recycling of some prominent plastic wastes into cost-effective rehabilitation materials with desirable performance characteristics. Phase I research evaluates the technical feasibility and economical viability of developing polymer concrete rehabilitation materials through depolymerizing impure and color post-consumer PET wastes. For this purpose, PET scrap sources and depolymerization process capable of generating unsaturated polyesters with acceptable processability and clear-cast resin characteristics will be identified. Optimum composition of polymer concretes incorporating recycled polyester binder will then be determined based on set characteristics, short-term engineering properties, and cost. Finally, market potentials of recycled polyester concrete will be determined through technical and economical evaluations against conventional rapid-setting rehabilitation materials.
