Paragraph starter
The incorporation of fibres into cementitious composites, as evidenced by research into fibre-reinforced concrete (FRC), offers a significant pathway to enhance material performance. Studies indicate that the addition of various fibre types, including steel, glass, carbon, and synthetic polymers, can substantially improve key mechanical properties such as ultimate tensile strength, toughness, and flexural strength by effectively intercepting micro-cracks. This enhancement is contingent upon the specific fibre characteristics (type, content, geometry) and the overall composite mix design, suggesting that tailored material solutions are achievable for demanding applications.
