Mitigating Cracking in Ultra-High Performance Concrete (UHPC) Bridge Connections
| 项目名称： | Mitigating Cracking in Ultra-High Performance Concrete (UHPC) Bridge Connections |
| 摘要： | In the proposed project, we are joining expertise in concrete mechanics (Tatar) and concrete durability (Rajabipour) to (1) develop and investigate 3D-printed formwork liners for repeatable surface-texturing of NC substrate in the connection region to enhance mechanical bond strength between UHPC and NC; and (2) investigate methods of reducing shrinkage in UHPC to mitigate interfacial and cohesive cracking. The findings from this work will improve the reliability of bridges constructed utilizing ABC techniques. The project, therefore, contributes to improved durability and extended life of transportation infrastructure, one of the primary objectives of CIAMTIS. |
