Development of supplementary cementitious materials from Algerian kaolin: elaboration of metakaolin and assessment of pozzolanicity

Researches on the use of metakaolin, as a supplementary cementitious material (SCM), are growing worldwide due to its environmental and technical benefits. Metakaolin is usually obtained by calcining kaolinitic clay; however, the thermal cycle of calcination should ensure the optimal kaolin to Metakaolin conversion. This experimental investigation aims to examine the effect of calcination parameters on two Algerian kaolins (KT1 and KT2), used to...
