Advanced Admixtures from Industrial Waste Products for Sustainable High-Performance Concrete
|Interdisciplinary Areas:||Innovation and Making, Smart City, Infrastructure, Transportation, Power, Energy, and the Environment
High-performance concrete (HPC) used for advanced infrastructure applications (bridges, dams, ultra-tall buildings) has 2-3 times the carbon footprint of conventional concrete mixtures due to the greater amount of cement required to achieve higher compressive strengths. Increasing the service life of HPC structures by including internal curing agents and other chemical admixtures is one proven way to reduce its carbon footprint. And chemical admixtures that are themselves more sustainable, including those derived from industrial waste or by-products, are expected to further reduce the overall carbon footprint of HPC. The goal of this project is to design and optimize a new class of recycled admixtures from environmental remediation efforts for the creation of more sustainable HPC, including reclaimed hydrogel and cellulosic particles. Lab-scale experiments and multiscale material characterization will be performed to identify key processing-structure-property relationships, including important HPC-admixture chemical and physical interactions and the internal curing performance of recycled admixtures after different preprocessing steps. Life cycle and technoeconomic assessments will be used to quantify overall environmental impacts.
