Abstract

Megatrends in infrastructure development will increase in cement manufacturing, which is currently one of the hardest sources of CO2 emissions to reduce. However, cementitious materials like Ground Granulated Blast Furnace Slag (GGBS) are being used to enhance sustainability in the construction sector. GGBS is a cementitious substance that is utilized in concrete to a limited extent and is a by-product of the iron-producing blast furnaces. It is extremely important for boosting concrete’s durability and strength. Its major benefit is the ability to slow down the hydration process thereby impacting the setting time of concrete. Even though multiple studies have looked at various areas like evaluating the reduction of cement use, reduction in CO2 and reduction in cost when the optimum percentage of GGBS is used in the mix design. Thus, the aim of the study is to analyse the economic and environmental impacts of GGBS as a partial substitute in concrete in Pune Metro Project. In order to achieve this goal, different applications of GGBS from past literature are examined. Then the suitability of GGBS is assessed to propose a mixed design by using different percentages of GGBS. Further, the optimum GGBS replacement results are examined to check the economic and environmental viability in the context of the Pune Metro Project.
