Currently cement is the most important material in the construction sector. Ordinary Portland cement is one of the main ingredients used for the production of concrete. Unfortunately, production of cement involves emission of large amounts of carbon-dioxide gas into the atmosphere, a major contributor of greenhouse effect and consequent global warming. While, cement typically comprises only 12% of the concrete mass, it accounts for approximately 93% of the total embodied energy of concrete and 6% to 7% of the world wide Carbon dioxide (CO2 ) emissions. Hence, it is of utmost importance to either search for another cementitious material or partially replace it by some other material. Currently there is a trend of usage of waste products such as fly ash from coal industries, GGBS from iron smelting process, paper ash from paper industry etc as supplementary cementitious materials to enhance the properties of concrete while also effectively reducing the carbon foot print. Ground Granulated Blast Furnace Slag (GGBS) is a by-product from iron smelting process using the blast-furnace. The present paper is prepared to study the effect on compressive strength of concrete due to partial replacement of cement with GGBS as supplementary cementitious material while using master REHO build 823PQ.
