Abstract Geopolymer mortar is a type of mortar that is
and infrastructure development drive up demand for building materials.
made using geopolymer binders instead of traditional cementbased binders. Geopolymer binders are typically derived from industrial by-products or natural materials and have lower environmental impact compared to cement. Geopolymer mortars offer high strength, durability, and chemical resistance properties, making them suitable for a variety of construction applications. Geopolymer Concrete has gained attention to the development of pavement repairs, Airport highways and other civil engineering structures. In this paper a comprehensive study was carried out for compressive strength of Geopolymer mortar using Fly Ash. The compressive strength of Geopolymer mortar prepared by replacing 100% cement with Fly Ash was checked. Alkali activators such as sodium hydroxide and sodium silicate were used as binders. Compressive strength were checked at 7 days and 14 days by performing compression test and it was observed that from the result of optimum molarity dosage of M ,the compressive strength of Geopolymer.
The building sector also faces a great deal of difficulty due to the loss of natural resources, including the supply of highquality aggregates for the manufacturing of concrete. Conventional river sand mining has resulted in habitat destruction, bank erosion, and environmental damage. In addition, the lack of appropriate aggregates has led to increased expenses and logistical difficulties for building projects. Examining sustainable aggregates and alternative binder systems that provide performance on par with or better than traditional materials while reducing their environmental impact is imperative in light of these difficulties. By using locally accessible minerals and industrial by-products, geopolymer technology offers a creative solution to these problems by producing high-performance mortars and concrete with a lower carbon footprint and resource usage.

With potential advantages in terms of performance, economy, and the environment over traditional Portland cement-based mortar, geopolymer mortar has become a viable substitute. Through a process known as geopolymerization, inorganic polymers known as geopolymers are created from aluminosilicate precursors, such as fly ash, slag, or other industrial by-products. Geopolymerization can be accomplished at ambient temperature or mild heat, resulting in reduced energy consumption and CO2 emissions than Portland cement, which requires high-temperature calcination and releases considerable volumes of CO2.
1.INTRODUCTION In order to reduce environmental deterioration and address climate change concerns, the global construction industry has been under increasing pressure to embrace sustainable techniques and materials in recent years. The creation of substitute binders for Portland cement, which is notorious for its high carbon footprint and energy-intensive manufacturing process, is one area of great interest and innovation in the field of sustainable building materials. A viable option that provides a sustainable substitute for conventional cement-based materials is geopolymer technology.
2. THE METHODOLOGY FOLLOWED IN THIS PROJECT
The manufacture of Portland cement, a vital component of traditional mortars and concrete, accounts for a sizeable amount of the world's carbon dioxide (CO2) emissions. Hightemperature kiln firing is a step in the process that releases CO2 as a byproduct and consumes a significant amount of energy. In addition, habitat devastation and environmental degradation are caused by the mining of raw minerals like limestone. There is a pressing need to lessen the environmental impact of cement production as urbanization
