Research Projects

Hydraulic infrastructure, such as spillways, sluice gates, and canals, faces critical challenges from abrasion and erosion caused by high-velocity water and sediment impact. This project focuses on developing an optimized form of Engineered Cementitious Composite (ECC), commonly known as bendable concrete, specifically tailored for hydraulic applications. ECC's unique properties, including high ductility, controlled microcracking, and self-healing abilities, make it an excellent candidate for enhancing abrasion resistance while maintaining flexibility and durability. By leveraging its dense microstructure and strain-hardening behavior, the proposed ECC will improve the resilience and longevity of hydraulic structures. The project aims to design and evaluate ECC mixes with cost-effective materials such as fly ash, slag, rice husk ash, and natural fibers like jute and coir to enhance sustainability. A series of experimental trials will assess mechanical properties such as compressive strength, tensile strength, fracture toughness, and abrasion and erosion resistance. Advanced methods, including microstructural analysis using scanning electron microscopy and X-ray diffraction, will provide insights into the fiber-matrix interactions and hydration processes. This will ensure the material achieves optimal performance under hydraulic conditions. Through a carefully planned methodology, the project will address the limitations of conventional hydraulic concretes, such as brittleness and overdesign, by offering a material that is both durable and cost-efficient. The ECC will undergo comprehensive testing for durability, including water permeability and erosion resistance, to validate its performance under real-world conditions. Additionally, the use of supplementary cementitious materials and natural fibers will significantly reduce the material's environmental impact, aligning the project with sustainable development goals. The outcomes of this research will contribute to the advancement of hydraulic infrastructure by providing a durable, flexible, and eco-friendly alternative to traditional materials. The findings will also support the development of guidelines for mix proportioning and applications of ECC in hydraulic settings. By engaging with industry stakeholders and publishing in high-impact journals, the project will facilitate knowledge transfer and promote the adoption of ECC in critical infrastructure projects across India and beyond.
