A demand for more ecologically friendly practices has made investigation of sustainable and eco-friendly building materials essential. In this work, the characteristics of concrete made with waste materials as additives—alccofine, bagasse ash, and coconut fiber—are examined. Alccofine, a byproduct of distillation of alcohol, was used in instead of a portion of cement, and bagasse ash, a byproduct of sugarcane industry, was used in place of fine aggregate. In order to improve the mechanical and fracture resistant characteristics of the concrete, coconut fibers were used as reinforcement. To measure the compressive strength, tensile and flexural strength of concrete specimens, and various mix proportions were prepared and analyzed. The experimental findings showed that the characteristics of concrete were significantly enhanced by the addition of alccofine and bagasse ash. The specimens' acceptable compressive, tensile and flexural strength values suggested they were suitable for structural applications. Further, the use of coconut fibers improved the concrete's strength and fracture resistance much further. The study demonstrates the possibility of using alccofine, bagasse ash, and coconut fiber as additives in the manufacturing of concrete to improve its strength properties. By minimizing waste production, the use of these waste products not only encourages sustainable practices but also has economic advantages by lowering the need for conventional resources. Additionally, the use of coconut fibers improves the concrete's overall strength and functionality. These results open the door for improvements in the strength-enhanced concrete technology sector by offering insightful information for the production and application of eco-friendly building materials.
