Інноваційні методи відновлення критичної інфраструктури в україні на основі сучасних матеріалів і технологій critical infrastructure in ukraine based on advanced materials and technologies

Abstract

The relevance of the study is determined by Ukraine's urgent need to develop scientifically sound approaches to restoring critical infrastructure after large-scale destruction caused by Russian military aggression. Reconstruction should be based not only on rapid restoration of functionality, but also on ensuring the durability, energy efficiency, and technological sustainability of structures. In this context, the introduction of modern materials and digital technologies is a decisive factor in increasing the reliability of engineering systems and the adaptability of infrastructure to future challenges. The purpose of the article is to analyze innovative methods for restoring Ukraine's critical infrastructure based on the use of modern materials and digital technologies, taking into account the requirements of sustainability, energy efficiency, and safety. The research methodology is based on systemic, structural-functional, and comparative-analytical approaches using expert assessment methods, technical-economic analysis, and life cycle modeling of engineering structures. To summarize the practice, cases of Ukrainian and international reconstruction projects were used, covering ultra-high performance concrete (UHPC), fiber-reinforced polymer (FRP), 3D printing, monitoring systems, and digital twins technologies. The results of the study consist in identifying the structural components of the restoration process, systematizing the potential of modern materials and technologies, and justifying the advantages of digital integration in restoration processes. It has been proven that the use of UHPC, FRP reinforcement, self-healing cements, 3D printing technologies, and digital modeling contributes to a 30–50% increase in structural strength, a 40–60% reduction in reconstruction time, and a 25% reduction in operating costs. The study emphasizes the need to transition to a normatively agreed and digitally integrated reconstruction system, within which innovative materials and technologies become the standard of state technical policy, rather than an exception to it. It has been established that effective restoration requires the unification of regulatory documents, the development of local production, and the creation of a single center for digital monitoring of critical infrastructure facilities. Prospects for further research are related to the development of national standards for the certification of innovative materials, the introduction of artificial intelligence systems in the monitoring of structures, the creation of a national platform for digital twins, and the development of a new generation of educational programs for engineers and managers in the field of sustainable reconstruction.
