Clinker substitution takes hold in Africa12 May 2023, Published under Cement NewsGhana's cement producers have struck out on a decarbonisation and low-carbon cement path. By using local resources for raw materials and reducing the clinker factor, cement manufacturers are targeting reduced imports of clinker and lower cement prices, as well as the benefits of CO2 reduction. This week the Director-General of Ghana Standards Authority, Professor Alex Dodoo, confirmed that plans are underway to build factories that can manufacture a substitute for clinker. "We have publishe... |
The potential of activated clays in cement10 August 2021, Published under Cement NewsOne of the pathways to a more sustainable cement industry is the reduction of the clinker factor in cement. The use of thermally-activated clays not only reduces the clinker content but also lowers CO 2 emissions as a result of dihydroxilation instead of dicarbonation and other energy savings. By Dr Carlos Aramburo, Carlos Aramburo Consultant, Colombia; Luiz Felipe de Pinho, Dynamis, Brazil; Dr Rafael Talero, SACACH SL, Spain, and M Pilar de la Torre, Carlos Aramburo Consultant, Spain. ... |
Boosting mill performance02 February 2021, Published under Cement NewsReducing the clinker factor without compromising quality and the rising demand for high-performance cements are great challenges for the fine grinding technology used in cement plants. As part of its green cement plant project, thyssenkrupp has expanded its product range with the polysius® booster mill. While one cement producer has already integrated the mill into an existing grinding circuit, several others have tested the mill since August 2020 and are checking results in terms of specifi... |
New analytics for MCCs16 November 2020, Published under Cement NewsNew analytical methods to characterise the inner particle size distribution (iPSD) of (multi-)composite cements (MCC) have been developed by the Institute of Nonmetallic Materials in Germany, aimed at producing higher-substituted cements with improved efficiency and performance. By Dr Johannes Unseld and Prof Dr Albrecht Wolter, Institute of Nonmetallic Materials, Clausthal University of Technology, Germany. Figure 1: reference limestone and the backwards calculated limestone PSD ... |
Into the future19 July 2018, Published under Cement NewsThere is no way we can imagine the world without cement and concrete. From 30 years ago, when International Cement Review was first published, until today, cement production on the planet has quadrupled. Depending on regional developments this volume may more or less stabilise going forward or even exhibit further growth. In any case, the cement industry will continue to lower the CO 2 footprint of cement and concrete. By Dr Martin Schneider, VDZ, Germany. Figure 1: cements containin... |
