| In recent years, with the advancement of sustainable development principles for ecological environments, "ecological concrete" has emerged as a groundbreaking innovation. Its "Shaqima"-like porous structure not only ensures structural integrity but also creates habitable niches for organisms, seamlessly integrating environmental and engineering benefits.In its preparation, ecological concrete employs a diverse range of constituent materials: solid waste materials such as discarded oyster shells and recycled aggregates serve as coarse aggregates, while natural pozzolans (e.g., volcanic ash) act as fine aggregates. Performance optimization is achieved by systematically regulating parameters like aggregate gradation, water-binder ratio, and mix proportions. Innovative mixing techniques have also been developed, including pan mixing and spray application methods.Mechanically, its compressive, tensile, and freeze-thaw resistance strengths can be enhanced through material modification, fiber reinforcement, and pore structure optimization. These technical adjustments ensure robust performance across diverse environmental conditions.In practical applications, ecological concrete has gained wide adoption in slope protection engineering, water purification systems, marine ecological restoration projects, and urban construction. By integrating engineering functionality, ecological sustainability, and landscape design, it creates synergistic advantages that benefit both infrastructure and the environment.Looking forward, the development of ecological concrete must address key challenges such as long-term durability and environmental adaptability. Moving toward a trajectory of "low-carbonization, functionalization, and intelligence," it is poised to play a pivotal role in advancing green infrastructure and supporting global sustainability goals. |
