Abstract : Classic concrete and traditional Self-Compacting Concrete typically demonstrate inadequate strength to withstand tension, resistance to breaking, and durability, resulting in a higher susceptibility to cracking and deterioration when exposed to dynamic or severe environmental conditions. Fiber-reinforced blended SCC has better mechanical properties and durability. It performs well under stress, impact, and tough conditions, which makes it more suitable for durable and resilient construction projects. This study examines the performance of self-compacting concrete (SCC) incorporating ternary blends of Fly Ash (FA) and Rice Husk Ash (RHA) as supplementary cementitious materials, reinforced with steel, basalt, and sisal fibers. The methodology involves assessing workability, mechanical strength, and durability, along with finite element analysis (FEA) using ANSYS to model stress–strain and load-deflection behavior. Studies show that fibers increase toughness, and tensile capacity, whereas FA and RHA improve sustainability and long-term strength. Combining natural and artificial fibers yields complementing benefits and provides a practical path to sustainable, high-performance concrete.
