Project description

The aim of this project is to develop a new class of self-healing cementitious composites (SHCC) with ultra-high ductility and durability that can autonomously heal cracks developed in the concrete, due to shrinkage, free-thaw damage, and service loading. The superior ductility and durability of SHCC can accommodate pavement and bridge structures deformation imposed by concrete shrinkage, temperature fluctuation, etc. As such, this class of SHCC materials provide a cost-effective solution to pavement and bridge rehabilitation as well as new construction projects.
