Abstract: The production of Portland cement causes a substantial environmental impact, since the calcination of limestone results in high emissions of carbon dioxide. The use of supplementary cementitious materials such as calcined clays as partial replacement for Portland cement offers a solution to limit this environmental impact. This paper investigates four clays from deposits in central Germany with the aim of obtaining pozzolans for the production of Portland- pozzolana cement. The results obtained show that the calcined clays possess pozzolanic proper- ties, which differ depending on calcination temperature and the relative amounts of kaolinite and 2:1 clay minerals.
