Special Issue Information

Dear Colleagues,

Coastal and offshore infrastructure—encompassing building structures, bridges, marine oil and gas platforms, wind turbine towers and substructures, electrical substations, and transmission towers—faces unparalleled durability challenges. Prolonged exposure to harsh coastal environments, characterized by high humidity, salt fog, UV radiation, and cyclic loading, leads to accelerated degradation, primarily through corrosion. This significantly compromises structural integrity, safety, and service life while increasing maintenance costs and environmental risks. This Special Issue welcomes the submission of high-quality original research and review articles dedicated to advancing our understanding and the mitigation of durability issues in these critical assets.

We aim for this Special Issue to serve as a forum for papers focused on the following themes:

  1. Degradation Mechanisms:

(1) Studies on atmospheric, splash zone, and submerged corrosion mechanisms for steels, concrete, and advanced composites.

(2) Stress corrosion cracking, corrosion fatigue, and multi-factor degradation models.

(3) Impact of microclimates, climate change, and extreme weather events on deterioration rates.

  1. Protection Strategies and Advanced Materials:

(1) Coating Technology: Development and evaluation of novel coatings (e.g., graphene-enhanced, self-healing, superhydrophobic), multi-layer protection systems, and long-term performance validation.

(2) Corrosion Prevention: Advances in cathodic protection, corrosion-resistant alloys (e.g., duplex stainless steels), and surface treatments.

(3) Durable Concrete: Use of supplementary cementitious materials, corrosion inhibitors, non-metallic reinforcements, and performance of concrete in aggressive chloride-laden environments.

  1. Monitoring, Assessment, and Lifecycle Management:

(1) Novel sensors, non-destructive testing (NDT) techniques, and remote monitoring for early corrosion detection.

(2) Predictive modeling for remaining service life and reliability-based lifecycle assessment.

(3) Robotics and AI-enabled inspection and maintenance strategies.

  1. Case Studies and Forensic Engineering:

(1) In-depth analysis of field performance, failure investigations, and lessons learned from existing coastal infrastructure.

(2) Long-term exposure trials and data from real-world service.

A Comparative Study on the Compressive Mechanical Properties of Modified Raw Bamboo Squares and Carbonized Bamboo Squares as Coarse Aggregate in Concrete

Bamboo is widely available and renewable. Using bamboo blocks to partially replace coarse aggregates in the production of concrete solid bricks shows promising application prospects in areas such as nonload-bearing wall materials. However, as a natural biomass material, bamboo squares have disadvantages such as susceptibility to decay, water absorption, swelling, and drying shrinkage, necessitating modification when used as concrete coarse aggregate. This study subjected raw bamboo squares to high-temperature carbonization. The compressive performance of concrete made with these carbonized bamboo squares was first tested and compared with concrete containing raw bamboo squares. Subsequently, both raw and carbonized bamboo squares were modified using conventional methods: polyvinyl alcohol (PVA) treatment, epoxy mortar (EM) treatment, epoxy resin (EPR) treatment, water glass (WG) treatment, and glutinous rice glue treatment. Modified bamboo block concrete specimens were prepared, and their compressive strengths were tested and compared. The results indicated that the compressive mechanical performance of carbonized bamboo block concrete consistently outperformed that of raw bamboo block concrete across all substitution rates. Specifically, the optimal modification method—using epoxy mortar (EM) encapsulation—significantly enhanced the mechanical properties. At a high volumetric replacement rate of 30%, the EM-modified carbonized bamboo concrete achieved a compressive strength of 27.79 MPa, which is 15.1% higher than that of identically treated raw bamboo concrete and far exceeds the standard MU7.5 grade requirements. These quantitative findings provide a solid experimental and theoretical basis for the high-value application of bamboo squares in sustainable concrete solid bricks. Full article

This study investigates the preparation and performance of ultra-high-performance concrete (UHPC) incorporating manufactured sand as a full replacement for quartz sand. The mix design was optimized by integrating the compressible packing model (CPM) with an orthogonal experimental design. The influence of stone powder content in manufactured sand—0, 5, 10, and 15% by mass of fine aggregate—on fresh-state fluidity and 7d-mechanical properties was systematically evaluated. Hydration products and microstructural features were analyzed using X-ray diffraction (XRD), scanning electron microscope (SEM), and mercury intrusion porosimetry (MIP). Results show that the manufactured sand-based UHPC achieved a fresh-state fluidity of 185 mm and a 7-day compressive strength of 152.4 MPa. Both fluidity and compressive strength exhibited a unimodal trend with increasing stone powder content, reaching maxima at 10%. Microstructural analysis revealed intimate interfacial bonding between unhydrated particles and calcium silicate hydrate (C–S–H) gel; notably, the UHPC matrix with 10% stone powder displayed the densest microstructure. MIP results further demonstrated that an optimal stone powder content effectively reduced total porosity, with the lowest overall porosity and the highest volume fractions of harmless (≤20 nm) and less harmful (20–100 nm) pores observed at 10%. These microstructural refinements collectively underpin the superior mechanical performance of manufactured sand-based UHPC. Full article

Coastal wind turbines operate under severe salt spray, high humidity, and wind-driven erosion, which accelerate coating degradation and corrosion-induced cracking. In such environments, corrosion defects exhibit blurred boundaries, weak textures, and significant scale variations, challenging object detectors in small-target localization and precise boundary regression. To address these limitations, this study proposes CoastCor-Net, an enhanced YOLOv11-based framework that improves spatial–semantic alignment, boundary representation, and channel–spatial dependency modeling. The architecture integrates three complementary modules to enhance boundary sensitivity, spatial–semantic consistency, and cross-channel interaction: a Decoding-Driven Enhancement Block, a Complementary Feature Alignment Module, and a Channel-Transposed Coordinate Attention module. Extensive experiments on the Wind Turbine Blade Damage Dataset show that CoastCor-Net achieves 84.7% mAP@0.5 and 54.1% mAP@0.5:0.95, surpassing YOLOv13n by 3.2 percentage points in mAP@0.5 and improving AP_damage by 5.2 percentage points. The framework also demonstrates strong robustness under composite coastal perturbations. These findings highlight the practical effectiveness of structured multi-level feature enhancement for reliable and high-precision blade inspection in complex coastal environments. Full article

In this review, the application of microbially induced calcium carbonate precipitation (MICP) for repairing coal mining-induced cracks in loess soils was summarized, and its objectives, main findings, and key challenges were highlighted. First, the formation characteristics and engineering demands of mining-induced loess cracks were analyzed, and the limitations of existing repair methods in terms of durability, adaptability, and environmental impact were emphasized. The advantages of MICP for soil stabilization, crack sealing, and ground improvement were presented, demonstrating its potential for use in the remediation of cracks in loess. Key challenges in practical implementation, including uneven injection, clogging, environmental constraints on microbial activity, ammonia byproduct risks, and insufficient long-term stability assessment, were discussed. Overall, MICP offers a sustainable and effective strategy for loess crack repair, providing a promising approach for ecological restoration and geotechnical reinforcement in mining-affected regions.
