Abstract: With the growing need for construction materials, Portland cement manufacturing increases year after year. The global production of Portland cement is increasing by 3% every year. As a result, the amount of carbon dioxide released into the atmosphere during the manufacture of Portland cement is increasing. The manufacture of Portland cement emits roughly 1.35 billion tonnes of greenhouse gases each year, accounting for about 7% of overall greenhouse gas emissions. Furthermore, after aluminium and steel, Portland cement is one of the most energy-intensive construction materials. Cement, fine aggregate, coarse aggregate, and water are all used for concrete. Concrete is the world's second most consumed substance, behind water, due to its importance in the building of infrastructure. Because concrete is such a versatile material that it may be used for a wide range of applications in a variety of environments, regular concrete may not provide the desired quality, performance, or durability. By substituting concrete with suitable pozzalonic material, it is also possible to minimise construction costs and improve concrete performance without losing its original features. This article examines the use of ground granulated blast furnace slag in place of cement (GGBS). The main objective of this study is to investigate the strength and durability parameters of geopolymer concrete for concentration of NaOH in terms of molarity (M). for each mix sizes of cubes, were casted and tested. For strength at the age of 4,8,12,18,24 hours and for durability at the age of 30 days.
