Dual Effects of Brown Algae Impurities on Coral Concrete: Sulfate Resistance Decay and Multiscale Predictive Modeling
In island construction, the application of coral aggregate concrete (CAC) is challenged by marine biological impurities, particularly brown algae, which impact material performance. This study systematically investigates the effects of brown algae content (0%–6%), water-to-cement ratio, and sulfate ion wet–dry cycl...
