Results indicated that the cooling pattern of the slag significantly affects the particle morphology and phase formation, which determines their usage and utilisation. The chemical, mineralogical, physical, thermal and morphological properties of four different slags generated under different cooling condition are evaluated for recycling to cement and aggregate application. The present research provides an understanding of the two different types of slags of water quenched granulated slag and air-cooled slag that are generated from iron making process through the blast furnace route.
Blast furnace slag is a by-product of the iron-making process while producing pig iron. Efficient utilisation and recycling of industrial waste along with minimum exploitation of natural resources are major challenge towards the circular economy and sustainability of the planet.
