Abstract :
    The increasing need to develop sustainable urban infrastructures that are resistant to environmental factors and operational loads has provided the basis for the use of new self-healing materials in hydraulic engineering. These materials, due to their ability to automatically repair cracks and reduce the need for frequent repairs, can play an important role in improving the long-term performance of urban water supply networks. The aim of this study is to compare the effects of geotechnical and concrete environments on the performance of self-healing materials in sustainable urban hydraulic systems. In this study, using an analytical-experimental framework, samples of self-healing materials were subjected to simulated conditions of geotechnical and concrete environments, and parameters such as mechanical durability, crack healing rate, permeability, and hydraulic performance were measured. The results show that the interaction of materials with the geotechnical environment, under the influence of moisture variables and soil stresses, has significant effects on the self-healing process, while the concrete environment, by presenting different loading levels and moisture transfer boundaries, provides a different response in the healing efficiency of the materials. These differences are such that the selection of the appropriate type of materials should be made according to the type of use and environmental conditions. The results of this research show that the targeted use of self-healing materials, especially in diverse environmental conditions, can help increase durability, reduce maintenance costs and increase the stability of urban hydraulic networks. These findings can be a guide for sustainable planning and design in civil engineering and water management in cities.
