Enhancing the Resiliency of Pavement Infrastructure Built on Sulfate-Rich Expansive Soil Subjected to Climate Change (Jul 2024, MPC-24-530)
The study aimed to understand the impacts of extreme climatic conditions such as prolonged droughts and intense precipitation due to climate change on the resilience of civil infrastructures like embankments. The knowledge of unsaturated soil mechanics and soil chemistry is integrated to determine the...
Calcium Sulfoaluminate Cement Concrete for Prestressed Bridge Girders: Prestressing Losses, Bond, and Strength Behavior (Dec 2019, MPC-19-401)
Calcium sulfoaluminate (CSA) cement was used to cast a prestressed voided deck slab bridge girder. The rapid-set properties of CSA cement allowed the initial concrete strength to reach the required 4300 psi needed in order to cut the prestressing strands 6.5 hours after casting. Prestress losses were...
