Abstract

The utilization of fly ash and bottom ash as alternative materials in construction has expanded in response to sustainability imperatives and increasing volumes of industrial by-products. This study consolidates and critically organizes existing scientific knowledge to clarify the relationships between material characteristics, mechanical performance, and sustainability considerations associated with fly ash and bottom ash. The analysis demonstrates that their mechanical behavior is highly dependent on physical–chemical properties, mixture design, and environmental context, indicating that performance cannot be generalized across applications. Although environmental benefits are frequently emphasized, sustainability is often framed in a simplified manner, with limited integration of life cycle impacts, social dimensions, and institutional constraints. The findings also reveal methodological inconsistencies and conceptual gaps that hinder knowledge transfer and practical implementation. By structuring dispersed evidence into a coherent analytical perspective, this study contributes to a clearer understanding of the conditions under which fly ash and bottom ash can be responsibly utilized. The outcomes provide a foundation for guiding future experimental development and supporting more informed decision-making in sustainable construction systems.

Abstract

Urban flooding represents a systemic risk emerging from the interaction between hydrological hazards, spatial transformation, and infrastructure vulnerability, demanding a management paradigm that transcends conventional engineering responses. This study develops a non-empirical conceptual framework for optimizing risk-based infrastructure management to strengthen urban flood resilience. The framework integrates infrastructure asset lifecycle management, disaster risk theory, and urban governance into a multilayer analytical model that explains causal relations among planning, implementation, maintenance, and adaptive capacity. A systematic literature synthesis and thematic-critical analysis were employed to construct stable conceptual propositions and evaluate internal coherence across disciplines. Findings indicate that preventive planning, adaptive asset management, institutional coordination, and participatory monitoring operate as interdependent mechanisms that reduce system fragility and enhance operational learning. The proposed model provides an analytical structure for evaluating infrastructure effectiveness without dependence on a single empirical context while preserving methodological rigor. This study contributes theoretically by linking risk governance with lifecycle infrastructure management and methodologically by offering a replicable conceptual synthesis for resilient urban systems.
