Development of high-ferrite cement: Toward green cement production
Journal of Cleaner Production, 2021Abstract The reduction of energy consumption and CO2 emissions is essential for the development of cement industry. To this end, this work designed and prepared a green cementitious material to reduce the clinkering temperature and CO2 emissions by increasing the amount of ferrite as an intermediate mineral in the cement production process.

Abstract The paper deals with control in the cement manufacturing. A short description of the technology is given first, then the control problems and applied strategies are discussed. After a short summary of the existing control systems technology the possible applications of advanced control algorithms are treated.

Airway inflammation in cement production workers
Occupational and Environmental Medicine, 2009ObjectiveCement aerosol exposure is associated with increased morbidity of airway disease among exposed workers. Our aim was to compare levels of inflammatory cells and soluble inflammatory markers in induced sputum samples from cement production workers between exposed and unexposed periods, and to compare these variables between cement workers and ...

Zero Emission Cement Production
ECS Meeting AbstractsThe cement industry accounts for 8% of global CO2 emissions due to the decomposition of limestone (CaCO3), which releases stoichiometric amounts of CO2, and the need for fossil-fueled kilns to operate at 1400 oC. Here, I will present the electrochemical production of a clinker precursor, Ca(OH)2, derived from the electrolytic decomposition of low ...

Research on portland-cement for asbestos-cement product
journal of the Japan Society for Testing Materials, 1954“Portland-cement” should possess distnctive properties according to the purpose, so that it's function as cement will be in full play.High durability should be the distinctive property of cement for asbestos-cement product, although it is required for cement for general contractions.Then, serious consideration must be carefully paid towards the ...

In 1990, the Danish cement industry was at almost the same level of production as it had been 30 years earlier. In between, production had doubled to an all-time high in 1973, only to decline again in the wake of the two oil crises. But since 1990, and despite ever-constant domestic demand, production has risen again, in 1996 reaching almost the peak ...

Exergy analysis of cement production
International Journal of Exergy, 2005In the present paper, cement production in Greece has been examined using the exergy analysis methodology. The major goal of the modern cement and concrete production industry is the minimisation of energy costs and environmental effects. The rational management of raw materials and energy requires analytical decision making tools that will provide the

One of the few European industries to experience a decline in material production has been the Austrian cement industry, with a fall of 40% between 1974 and 1998, accompanied by a decline in domestic cement consumption of about 20%. Austria’s cement industry therefore presents itself as an interesting field for analysing structural change and green ...

Wastepaper fibres in cement products
International Journal of Cement Composites and Lightweight Concrete, 1989Abstract Wastepaper is an acceptable reinforcement for cement products. At fibre loadings of approximately 12% by mass the air cured cement composite has flexural strength of 18.2 MPa, fracture toughness value of approximately 1.0 kJ/m 2 , water absorption value of 25% and a density of 1.43 g/cm 3 . Quality wood fibre reinforcement ( P.
