  282-CCL : Calcined Clays as Supplementary Cementitious Materials

  The most suitable path to achieve sustainability in cement production is the reduction of the clinker factor by adding Supplementary Cementitious Materials (SCM). The most common SCMs used today are fly ash, slag, and natural pozzolan. The reduction of steel production and phasing out of coal power plants has reflected in a significant decrease in the supply …

  201671 · Most of the clays were calcined in our laboratory, about 1 kg per batch, in alumina crucibles at 800 °C for 1 h in a high-temperature furnace (Borel FP1100). This calcination temperature was chosen to ensure complete dehydroxylation of kaolinite and to get the highest pozzolanic potential of calcined clay [1], [5].
