coke, and limestone. About 30% to 40% SiO2 and 40% CaO make up molten slag, which is nearly identical to Portland cement's chemical makeup. GGBFS will reduce carbon dioxide gas emissions in place of Portland cement. It is therefore a building material that is friendly to the environment. GGBFS is regarded as an environmentally beneficial material since it usually doesn't need to be processed before being used in concrete in modern thermal power plants. With GGBS, we can replace roughly 80% of the Portland cement in concrete. Improved resistance to sulfate attack, corrosion, and water impermeability are among the qualities of GGS. because of decreased heat hydration. It lessens the possibility of thermal fracture. It is more resilient and workable, but less permeable to other organizations.
necessary supplies are currently unavailable. Therefore, we must come up with a different plan of action by substituting other components for cement, fine aggregate, and coarse aggregate in the concrete. The most expanding component of concrete is cement. Cement manufacturing is responsible for more than 5% of the world's carbon dioxide emissions. This technique uses GGBS, an alternative source of cement a compressive analysis of the characteristics of concrete with GGBS partially substituting cement. Made in the blast furnace that produces iron, GGBS is a by-product. Blast furnaces are supplied with a precisely regulated mixture of iron ore, coke, and limestone and run at temperatures between 1500 and 1600 °C. It has an off-white hue. In this studies M35-grade concrete mixtures have GGBS replacement percentages of 20%, 30%, and 40% of the original cement. Strength measurements at 7 and 28 days include compressive strength. It is determined what percentage of GGBS substitution is ideal by comparing the strength to regular concrete.
1.2 Using Concrete with GGBFS: an improved and more robust basis. decreasing and managing heat cracking. lower heat-induced hydration. sustained development of strength. strengthened defenses against peaty, acidic substances. heightened resilience to salt and sulfates in the maritime milieu. These days, high-rise structures, bridges, and highways are the main uses for GGBS concrete.
Key Words: Ordinary Portland cement, GGBFS, Compressive strength, Design mix, conventional concrete.
1.INTRODUCTION:
2. AIM AND OBJECTIVE:
In the globe, concrete is undoubtedly the most frequently used building material, with almost six billion tons manufactured annually. in terms of individual consumption. There is only water in the area. The most significant material element in the constructed environment is concrete. Concrete with less embodied energy might benefit the economy and the environment greatly without sacrificing functionality or driving up costs. Portland cement, aggregates, and water are the three primary components of concrete. Although Portland cement typically makes up about 12% of the mass of the concrete, it accounts for around 93% of the total embodied energy of the material and 6–7% of global CO2 emissions. To minimize the unfavorable features, you can use some remedial steps.

Determine whether using GGBS instead of cement while building concrete is feasible. Examine how concrete cubes' compressive strengths behave. When substituting 20%, 30%, or 40% of the cement with GGBS, compare the outcome to conventional normal concrete and the number of cubes cast. Then, compare the qualities with standard mix M35. The goal is to determine the most cost-effective replacement percentage without compromising strength and to offer affordable building costs.
