Concrete is the most widely used construction material on the planet, with around six billion tonnes manufactured each year. In terms of per-capita usage, it is only second to water. However, both the damage caused by raw material exploitation and CO2 emissions during cement manufacturing harm the environment's long-term viability. This put pressure on researchers to find ways to reduce cement use by partially substituting additional materials for cement. These materials could be naturally occurring, industrial leftovers, or less energy-intensive byproducts. When these components (known as pozzalonas) are mixed with calcium hydroxide, they produce cement. Fly ash, silica fume, metakaolin, and crushed granulated blast furnace slag are the most regularly utilised pozzalonas (GGBS). It is necessary to investigate the performance of admixtures when mixed with concrete in order to provide a lower life cycle cost. The purpose of this work is to investigate the characteristics of M20 grade concrete with partial substitution of cement with ground granulated blast furnace slag (GGBS) at percentages of 10%, 20%, 30%, 40%, and 50%.
