Posterosion Performance of Seawater–Sea Sand Concrete: Synergistic Reinforcement by Ultrafine Metakaolin and Nano-TiO2 under Tidal Action
The direct use of untreated seawater and sea sand for concrete production may adversely affect the mechanical properties and durability of concrete, thereby limiting their widespread application in civil construction. To address this issue, this study has investigated the performance evolution of seawater–sea sand...
