  3. The European cement industry is committed to ensuring that society has sufficient cement to meet its needs, whilst at the same time reducing its fuel and raw material requirements and subsequent emissions. The use of waste materials in the cement industry, also referred to as co-processing, contributes towards achieving these objectives.

  4. Whilst the processes behind the use of Ground Granulated Blast Furnace Slag (GGBFS) as a substitute raw material is well understood the application of the material represents a considerable challenge for the plant designer from the intake of the granulated slag to the introduction of the ground material to the blended cement.

  5. The primary distinction among the three types is the percentage of slag they contain. Slag cement may contain portland cement (see on Wikipedia) or hydrated lime (or both) while the other two are blends of Portland cement and slag only. Blast furnace slag materials are generally available from slag processors located near iron production centres.

  12. Iron and steel ("Iron/steel") slag is a by-product of manufactur-ing iron/steel products.1) Almost all iron/steel slag generated in the course of iron/steel manufacture is effectively used in multiple ways, such as a raw material for cement, a road base course materi-al, a civil engineering work, and a raw material for fertilizer.

  13.  · The road Portland cement was prepared under laboratory conditions from the following raw materials: nickel slag, limestone, fly ash, clay, steel slag, gypsum, and fluoride. Nickel slag was acquired from a nickel slag storage yard of Delong Nickel Industry Company in Xiangshui economic development area, Jiangsu Province, China.

  14. The chemical composition of a slag varies considerably depending on the composition of the raw materials in the iron production process. Silicate and aluminate impurities from the ore and coke are combined in the blast furnace with a flux which lowers the viscosity of the slag.

  15. Raw Materials. The raw materials of die cement industry include limestone (about 45 per cent CaO content), slag from steel plants, sludge from fertilizer India's per capita consumption of paints is very low at 0.23 kg as compared to the US (25 kg), France (15 kg), …

  16. Worldwide, there are around 600 separate grinding plants in the cement industry. These receive their feed materials, such as clinker, slag, fly ash and other pozzolanas and intergrinding materials from various sources and are not preceded by an integrated clinker production line.
