An econometric analysis reveals that technical progress in India's cement sector has been biased towards the use of energy and capital, while it has been material and labor saving.
The results show that approximately 2.48t, 4.69t, and 3.41t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding...
The high quality of the magnesia cement compositions in comparison with Portland cement was justified based on the data obtained from laboratory analysis. View Show abstract
Barriers to Entry(high) • RAW MATERIAL -Cement being a high bulk and low value commodity, outward freight accounts for close to one fifth of the total manufacturing cost. In addition, for every tonne of cement produced, close to 1.7 tonnes of raw material is transported.
An approximate analysis for raw mix on ignited basis, or for clinker, is: CaO: 65- 68%: Si O2: 20- 23%: Al2O3: 4- 6%: Fe2O3: 2- 4%: MgO: 1- 5%: Mn2O3: 0.1- 3%: TiO2: 0.1- 1%: SO3: ... The second important raw material for cement production is clay.The main component of clay is formed by hydrous aluminium silicates.The chemical composition of ...
The cement production process emits approximately 0.9 tons of CO 2 per ton of cement (Hasanbeigi et al. 2010), accounting for about 5–8% of global CO 2 emissions and ranking as the second-largest CO 2 emissions source (Mikulčić et al. 2016; Kajaste and Hurme 2016).According to the Intergovernmental Panel on Climate Change (IPCC) report, the cement …
Bulk material handling is a major activity and bins for raw materials, intermediate products and finished cement must reliably provide controlled flows of materials upon demand. The tonnages of material to be stored at various process stages are outlined by Deolalkar in Chapter 13 of his book (Deolalkar,2009), while his Chapter 16 discusses the ...
Raw material blending is an important process affecting cement quality. The aim of this process is to mix a variety of materials such as limestone, shale (clay), sandstone and iron to produce ...

The materials routinely analyzed at the cement plant include cement raw ingredi-ents such as limestone and clay, clinker, cement, kiln feed, and kiln dust. Multielement standards, which bracket concentration of unknowns, effectively …
In other study, Xu et al. [3] have corrected the dried sludge by 138 10% of lime (LDS10) prior to be used as raw material for cement production. They have come out with the result that 15% of LDS10 could be a good substitution for the cement raw materials. Also, incorporation of LDS10 has shown less carbon dioxide emission.
The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing ...
Due to fast analysis speed, analyzing composition content of cement raw meal utilizing near infrared (NIR) spectroscopy, combined with partial least squares regression (PLS), is a reliable ...
