Abstract

Concrete is a construction material widely used in infrastructure development due to its high compressive strength and good resistance to various environmental conditions. However, in industrial environments, concrete is susceptible to degradation caused by chemical and biological processes, one of which is bio-corrosion. Bio-corrosion occurs as a result of the activity of acid-producing microorganisms that lower the pH of the concrete surface, damage the material matrix, and accelerate corrosion of the reinforcing steel. Industrial areas, such as regions with fertilizer plants and chemical industries, generate emissions and waste containing phosphorus compounds that can affect the durability of concrete. Phosphorus compounds play a dual role: they can accelerate bio-corrosion by serving as a nutrient source for microorganisms, yet under certain conditions they may also act as corrosion inhibitors by forming protective layers on reinforcing steel. This study aims to comprehensively examine the role of phosphorus compounds in concrete bio-corrosion within industrial environments. The method employed is a literature review that analyzes previous studies addressing bio-corrosion mechanisms, microbial activity, and the influence of phosphorus on concrete and reinforcing steel. The results indicate that concrete bio-corrosion is a complex phenomenon influenced by interactions among biological, chemical, and environmental factors. The role of phosphorus is highly dependent on the surrounding environmental conditions of the concrete; therefore, effective industrial environmental management is a crucial factor in maintaining the durability and service life of concrete structures. This review is expected to provide a scientific basis for mitigating concrete deterioration and supporting sustainable infrastructure management in industrial areas.

Abstract

Groundwater level fluctuations are a significant geotechnical factor influencing the stability and integrity of building foundations, particularly in coastal areas affected by seasonal hydrological cycle dynamics, tidal variations, and seawater intrusion. Lhokseumawe City, as an industrial and coastal residential area in North Aceh, is characterized by geological conditions dominated by water-saturated alluvial soils with low permeability, making it vulnerable to pore water pressure fluctuations, reductions in soil bearing capacity, and the risk of progressive subsidence. This study employs a systematic literature review method with an in-depth analysis of 22 national and international scientific references published between 2020 and 2025, obtained from ScienceDirect, SpringerLink, Scopus, and national engineering journal repositories. The review focuses on: (1) the relationship between seasonal rainfall patterns, tidal processes, and groundwater level fluctuations; (2) the quantitative impacts of groundwater level rise and decline on effective stress, foundation bearing capacity, and structural deformation; and (3) the mechanisms of seawater intrusion and its effects on reinforcement corrosion and concrete degradation in reinforced foundations. The synthesis results indicate that groundwater level rise due to extreme rainfall and high tides can increase pore water pressure by up to 20–30 kPa, reduce soil shear strength by approximately 35–40%, and decrease the bearing capacity of shallow foundations by 30–50%. Conversely, groundwater level decline resulting from excessive extraction induces clay soil consolidation with potential local subsidence of 1–3 cm/year, differential settlement, and structural damage in buildings that have been in service for several decades. Furthermore, seawater intrusion increases groundwater salinity, with chloride concentrations reaching 2,000–5,000 mg/L in coastal zones, thereby accelerating reinforcement depassivation and corrosion in reinforced foundations. These findings underscore the importance of adaptive foundation design, groundwater extraction control, and integrated seawater intrusion mitigation strategies to support the sustainability of coastal infrastructure in Lhokseumawe.

Abstract

Sulfate attack is a significant chemical degradation mechanism in concrete, particularly for structures located in industrial environments. This process occurs due to reactions between sulfate ions and hydrated cement compounds, such as calcium hydroxide and calcium aluminate, producing expansive products like ettringite and gypsum. The formation of these compounds causes volumetric expansion, cracking, strength reduction, and progressive deterioration of concrete structures. Industrial environments are highly susceptible to sulfate attack due to production activities that generate emissions and wastewater containing sulfur compounds. These sulfur compounds undergo transformation through the environmental sulfur cycle, increasing the availability of aggressive sulfate ions that attack concrete. Continuous sulfate exposure has a significant impact on the durability of concrete infrastructure, characterized by increased porosity and permeability, as well as a reduced service life of structures. This study aims to examine the mechanisms of sulfate attack on concrete structures and its relationship with the sulfur cycle in influencing infrastructure durability. The method employed is a scoping review, analyzing scientific literature from reputable databases and nationally indexed journals. The results indicate that the severity of sulfate attack is influenced by sulfate ion concentration, environmental conditions, and concrete characteristics. A comprehensive understanding of this mechanism provides a critical foundation for the planning, management, and maintenance of sustainable concrete infrastructure in industrial environments.

Abstract

Dissolved oxygen (DO) is a key indicator of water quality that critically determines the health of aquatic ecosystems and the effectiveness of natural water treatment processes. This study analyzes the role of DO in supporting sustainable drainage systems (SuDS) in the Krueng Cunda River, Lhokseumawe City, through a literature review and water quality analysis based on purposive sampling at five observation points. The analyzed parameters include temperature (29–33?°C), DO (6.3–7.7?mg/L), organic carbon (0.126–3.73%), pH (7.30–7.90), and total nitrogen (1.4–3.6?mg/L), compared with water quality standards according to Government Regulation No. 82 of 2001. The results show that DO levels in the Krueng Cunda River are within a good range (6.3–7.7?mg/L), corresponding to Class I–II, thus still supporting aquatic life and aerobic decomposition of organic matter. However, anthropogenic pressures from domestic activities and brackish aquaculture have the potential to reduce DO if not controlled through pollutant load management and enhancement of natural aeration. These findings highlight that the development of SuDS in the Krueng Cunda River should prioritize controlling organic pollution and designing drainage elements that promote aeration and the river’s self-purification processes.
