Biodeterioration and Chemical Corrosion of Concrete in the Marine Environment: Too Complex for Prediction

Microorganisms, Год журнала: 2023, Номер 11(10), С. 2438 - 2438

Опубликована: Сен. 28, 2023

Concrete is the most utilized construction material worldwide. In marine environment, it subject to chemical degradation through reactions with chloride (the important ion), and sulfate magnesium ions in seawater, biodeterioration resulting from biological (initially microbiological) activities, principally acid production. These two types of corrosions are reviewed failure attempts predict degree deterioration each noted. Chemical (abiotic) corrosion greatest splash zone coastal constructions, while phenomenological evidence suggests that tidal zones. There have been no comparative experiments determine rates microbial biofilm formation these Both microbiological concrete deteriorations complex not successfully modeled. The interaction between abiotic considered.

Опубликована: Май 7, 2024

The concept of ecology, historically rooted in the economy nature, currently needs to evolve encompass intricate web interactions among humans and various organisms environment, which are influenced by anthropogenic forces. In this review, definition ecology has been adapted address dynamic interplay energy, resources, information shaping both natural artificial ecosystems. Previously, 3D (and 4D) printing technologies have presented as potential tools within ecological framework, promising a new for nature. However, despite considerable scientific discourse surrounding printing, there remains significant gap research exploring between these directions. Therefore, holistic review incorporating principles into practices is presented, emphasizing environmental sustainability, resource efficiency, innovation. Furthermore, 'unecological' aspects disadvantages related legal aspects, intellectual property, legislation, well societal impacts, underlined. These ideas collectively suggest roadmap future practice. This calls more comprehensive understanding multifaceted impacts development responsible aligned with goals.

Design and Fabrication of Bio-Enhancing Surfaces for Coral Settlement

Architecture, Год журнала: 2025, Номер 5(1), С. 20 - 20

Опубликована: Март 20, 2025

Coral reefs are vital ecosystems facing rapid degradation. This research explores architectural design solutions for bio-enhancing modular prototypes to support coral attachment and growth. Inspired by polyps, nine biomimetic designs were created using Maya Rhinoceros 3D optimise surfaces settlement. A total of 75 (15 × 15 cm) fabricated, incorporating four materials—PETG, concrete, oyster clay—and seven colour variations—sand, translucent green, brown, red, pink, grey, reddish. The findings indicate that printing with PETG was the most efficient fabrication method but required structural long-term underwater testing, while concrete demonstrated potential self-sustaining structures. study highlights role in marine restoration, promoting biodiversity resource-efficient solutions. By integrating corals into design, these structures can self-grow adapt, reducing material consumption maintenance.
