Development of Novel Ultra-High Performance Engineered Cementitious Composites (UHP-ECC) for Durable and Resilient Transportation Infrastructure
| 项目名称： | Development of Novel Ultra-High Performance Engineered Cementitious Composites (UHP-ECC) for Durable and Resilient Transportation Infrastructure |
| 摘要： | For the design of structures, both strength and ductility of structural materials are of utmost importance to ensure safety and reliability of structures, particularly at extreme conditions. As such, endowing concrete with high strength and ductility capabilities could potentially allow for the design of civil infrastructure with concrete as the solo structural material. Recently, Ultra-High-Performance Engineered Cementitious Composites (UHP-ECC) have been proposed to overcome the limited ductility of Ultra-High-Performance Fiber-Reinforced Concrete (UHP-FRC) and produce cementitious composites with remarkable mechanical properties. The design of this emerging class of concrete materials are based on the combination of the micromechanics and fracture mechanics design concepts of ECC and the high particle packing density matrix design approach of UHPC. Through the combination of these, high strength and high ductility can be simultaneously achieved. The objective of this research project is to develop novel UHP-ECC materials utilizing readily available ingredients in Region 6. The development of such materials will provide the region with state-of-the-art cementitious composites that will be available for the construction and repair of transportation infrastructure as well as for further research and development. |
