A Review on Hybrid Fiber-Reinforced Self-compacting Concrete: Properties & Challenges

The material known as Hybrid Fiber Reinforced Self-Compacting Concrete (HF SCC) combines the advantages of SCC with several fiber kinds, including glass, steel, and synthetic fibers. This article provides an overview of HF SCC-related research and findings, focusing on new and challenging features, practical applications, sustainability, and design and technology developed for the HF SCC standards. The HF SCC study investigated the impact of fiber, fiber fraction, and composite design on performance, strength, toughness, and durability. Clinical studies have shown that adding fiber to SCC improves its mechanical properties including tensile strength, fracture toughness, etc. The interactions between the fibers and other components of the concrete matrix were analyzed to understand the mechanisms behind the development of HF SCC. Sustainability factors and environmental considerations are important in the development and usage of products. We conducted a life cycle valuation to assess the environmental influence of HF SCC and explore the usage of recycled materials and sustainable practices. The outcomes highlight the potential of HF SCCs to contribute to sustainable development by reducing carbon emissions, reducing waste and improving resource efficiency. Key outcomes from the above discourse include the recognition of Hybrid Fiber Self-Compacting Concrete (HFSCC) as a promising solution in construction, owing to its ability to enhance mechanical properties through the incorporation of various fiber types. Extensive research has deepened our understanding of HFSCC’s behavior and operation, highlighting its efficacy across diverse applications. However, further exploration is warranted to address research gaps, particularly in understanding penetration, shrinkage, and resistance to environmental factors. Promoting HFSCC adoption, advancing sustainable practices, and standardizing design and manufacturing processes are crucial steps towards realizing its full potential in the construction industry.
