Decarbonising construction with calcined clay11 September 2024, Published under Cement NewsOne of the ways Holcim is decarbonising construction is by increasing the use of calcined clays to further develop the company’s ECOPlanet low-carbon cements and enable large-scale low-carbon construction. The first ECOPlanet calcined clay cement was launched in La Malle, France, in 2021, with multiple additional product launches planned in 2024. By Amith Kalathingal and Rémi Barbarulo, Holcim Innovation Center, France. Calcined clay: the most reactive and most scaleable new mineral... |
thyssenkrupp Polysius and Schwenk collaborate on meca-clay development12 December 2023, Published under Cement Newsthyssenkrupp Polysius and Schwenk Zement have jointly developed a new process and technology that enables the activation of any type of clay without thermal energy and fossil fuels. The two companies recently presented meca-clay in Brussels, Belgium. The newly-developed meca-clay process enables the activation of all types of clay using only electrical energy, without the use of fossil fuels. With meca-clay, the potential of mechano-chemistry – that aims at making green chemistry bey... |
FLSmidth forms ECOClay partnership to fully electrify clay calcination27 April 2022, Published under Cement NewsTo further decarbonise the cement industry, FLSmidth and a series of leading industry experts have formed a new partnership called ECoClay TM . To reduce CO 2 emissions from cement production by up to 50 per cent, the ECoClay partners will develop and commercialise the technology needed to replace fossil fuels in the calcination of clay by fully electrifying the process. Current clay calcination processes have gained momentum in recent years – especially with FLSmidth’s flash calciner sys... |
Clay calcination – accelerating cement’s green transition30 August 2021, Published under Cement NewsWith the cement industry’s goal of working towards saving the planet, FLSmidth proposes a simple switch: replace 30 per cent of clinker with calcined clay for up to a 40 per cent reduction in CO 2 emissions. In this article the company outlines why the move is not only smart and efficient but is something almost every cement manufacturer could do right now. By Steven Miller, FLSmidth, Denmark. Figure 1: FLSmidth’s clay calciner system With seven per cent of all global carbon em... |
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.
