Because of its high tensile strength and environmental friendliness, banana fiber—a naturally occurring substance that is collected from banana plants—shows promise as a reinforcement in concrete. In this investigation, different concentrations of 0.5%, 1%, and 1.5% of banana fiber are added to the concrete. At 20%, 40%, and 60% concentrations, copper slag—a byproduct of copper extraction—is utilized to partially replace cement. At levels of 3%, 6%, 9%, and 12%, zeolite powder—a microporous alumino silicate mineral—is added as a supplement to enhance the qualities of the concrete and partially replace fine aggregate for 28, 56, and 90 days to assess split tensile strength and compressive strength.

1. INTRODUCTION One of the most popular building materials in the modern world, concrete is prized for more than simply its adaptability. It is the material of choice for building due to its strength, affordability, durability, and versatility. Concrete is therefore acknowledged as a reliable and secure substance that may be used in a variety of ways. It is frequently utilized in residential buildings, multistory business buildings, and infrastructure projects including highways and bridges. In order to construct load-bearing components like slabs, beams, and columns, concrete is essential. Cement, water, aggregates (such sand and gravel), and occasionally admixtures or additives to enhance performance are its main components. An inventive strategy to improve performance and sustainability is the use of copper slag in concrete as a partial substitute for cement. Because of its pozzolanic

copper—offers an environmentally benign substitute for conventional cement and adds strength and durability to concrete. In addition to lowering the environmental impact of producing concrete, this technique efficiently repurposes industrial waste by substituting copper slag for some of the cement, usually at concentrations between 20% and 60%. This method preserves or even enhances the mechanical qualities of concrete while lowering carbon emissions, conserving natural resources, and possibly lowering building costs. A sustainable method for improving the longevity and functionality of concrete is to partially substitute zeolite powder for fine aggregate. The high silica content, pozzolanic activity, and capacity to increase the strength and resilience to chemical attacks of concrete make zeolite, a microporous aluminosilicate mineral, valuable. Zeolite powder, usually in proportions between 3% and 12%, can be used to partially replace fine aggregate (such as sand) in concrete to improve binding qualities and create a denser microstructure, which lowers permeability and increases durability. This method offers potential advantages for structural applications, particularly in areas that demand high durability and chemical resistance, in addition to using environmentally acceptable materials and reducing the consumption of natural resources. Banana fiber, which is made from the stems of banana plants, is a natural, environmentally friendly reinforcement that improves the mechanical properties and sustainability of concrete. It is a great substitute for synthetic fibers in construction because of its high tensile strength, low weight, and biodegradability. When added to concrete in different concentrations (usually 0.5%, 1%, and 1.5%), banana fiber increases the material's tensile strength, crack resistance, and flexibility, which can prolong the lifespan of concrete structures and lower maintenance costs. This method not only repurposes agricultural waste, but also supports green building initiatives by reducing the environmental impact of construction and reliance on non-renewable resources.
