Aug 10, 2021 One 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 ...
