Effectiveness of Microbial Composite Strains in Reducing River Sediment

The accumulation of sediment in rivers and lakes can elevate riverbeds, leading to a reduction in river channel flood-carrying capacity, impairment of water conservancy project benefits, and destruction of aquatic ecosystems. Systematic dredging projects are required in the routi...

Shaking Table Test on Response of Prestressed Concrete Hybrid-Reinforced Solid Square Piles in Soft Versus Stiff Clay

Prestressed concrete hybrid-reinforced solid square (PCHSS) piles combine strands and rebars for improved ductility. This study presents large-scale shaking table tests (1:2 scale) on PCHSS pile–superstructure systems embedded in soft and stiff clay, subjected to four ground moti...

Insights into Early-Age Interfacial Bonding Improvement of Polymer-Modified Sulfoaluminate Cement Mortar: Roles of Polymer Film Formation and Hydration Regulation

In this study, a polymer-modified fast-hardening and early-strength cement-based repair material was proposed, using the polymer cellulose ether (HPMC), polymer dispersible polymer powder (VAE) and silica fume. The optimal mixing ratio of the three polymers was designed by an ort...
