The aim of the present work was to assess the emission of different persistent organic pollutants from a cement plant over a period of one year, under normal operational conditions. Thus, a long-term sampling device was installed in the clinker kiln stack of the cement plant. The factory uses petroleum coke as primary fuel, but also alternative fuels such as solid recovered fuel (SRF), automoti...

Cement powder size classification efficiency significantly affects quality of final product and extent of energy consumption in clinker grinding circuits. Static and dynamic or high efficiency air separators are being used widely in closed circuit with multi-compartment tube ball mills, High Pressure Grinding Rolls (HPGR) and more recently Vertical Roller Mills (VRM) units in cement plants ...

Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas; one ton of portland cement clinker production is said to creates approximately one ton of CO2 and other greenhouse gases (GHGs). Environmental issues are playing an impo...

Tobias Smollett’s final novel, The Expedition of Humphry Clinker, published in 1771, is commonly viewed as Smollett’s masterpiece, a mature work which marks a transition from the picaresque adventure narrative to the masterly handling of epistolary form. Part of Smollett’s achievement in Humphry Clinker is in re-fashioning the epistolary travel journal to the purposes of literary fiction while ...

The possibility of improving the physical and mechanical properties Portland cement with maximum clinker savings by optimizing composition hybrid additives is shown. It has been established that combining local mineral ingredients additive artificial origin Phosfozol allow saving low-clinker while maintaining its original grade 400.
