The comprehensive utilization of slag in the cement industry has mainly passed through three stages: The first stage (before 1995) granulated blast furnace slag was mainly used as a cement mixture. Mainly mixed grinding. The slag is difficult to grind, so the amount of cement in the cement is limited, generally not more than 30%.

This paper discusses the issues pertaining to the solid waste generation in Rourkela Steel Plant, Odisha in terms of volumes toxicity, challenges and efforts towards recycling and utilization in eco-friendly manner.
Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness. GBFS can be utilized in the cement …
The number of granulation plants for blast furnace slag has grown strongly. Since around 2000, the most important Chinese steel producers have been investing in granulation and grinding plants for blast furnace slag. It is currently estimated that 95 % of the blast furnace slag is granulated and used entirely in the cement and concrete industry.

Ground Granulated Blast furnace slag is a waste slag discharged from smelting of pig iron blast furnace. When smelting pig iron in the blastfurnace,we need add iron ore and fuel (coke), a flux. When the furnace temperature reached 1400 to 1600 ℃, the flux react with iron ore and produce pig ore and slag.
For example, it has been estimated that the use of 50% granulated BF slag in a cement mix reduces the CO 2 emissions from 1.2 to 0.54 t/t cement . If all the BF slag were directed to cement, this would constitute an approximate reduction in CO 2 of 435 Mt per year, with a value of over $6 billion in carbon credits. Utilization of Slags
Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production.
