Once cooled the molten slag solidifies to form glassy and/or crystalline minerals depending on the specific rate and method of cooling. Molten slag is collected in iron slag pots during the melting of raw materials in the electric arc furnace. The slag is then cooled by pouring it .
alternate fuels and raw materials (AFR) still remains a major area of concern. At present, the TSR (Thermal Substitution Rate) of the Indian cement industry ranges between %, while in some developed countries, this figure is as high as 60%. Use of Alternative fuels for meeting energy requirement is a sustainable initiative which can

Bangladesh: The Bangladesh Cement Manufacturers Association (BCMA) says a new import tax on raw materials and a distribution levy will increase the price of cement and place a burden on the construction industry. The new duties will add 8% to the existing 15% of valueadded tax (VAT) already liable on raw materials, according to the Daily Sun newspaper.
Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal.
Nov 21, 2019· From an environmental viewpoint, the use of slag cement in concrete serves to make concrete "greener." Not only can it be considered a recycled material, but it can also significantly reduce energy consumption and greenhouse gasses emitted in the production of concrete raw materials.
Green cement is a cementitious material that meets or exceeds the functional performance capabilities of ordinary Portland cement by incorporating and optimizing recycled materials, thereby reducing consumption of natural raw materials, water, and energy, resulting in a more sustainable construction material. One is Geopolymer cement.
One of the principal reasons for the outstanding success of the highpressure grinding roll in the cement industry is its low power requirement. Today, this mill is employed all around the world for the grinding of cement raw material, cement clinker and granulated blast furnace slag.
The energy, emissions and raw materials required to produce slag cement is a fraction of that needed for traditional portland cement. Replacing a portion of portland cement with slag cement – typically from 30% to 50% – significantly lowers the environmental impact of concrete.
