Almost half the papers presented at the 2010 SCMT conference in Ancona described replacement materials for cement in concrete. The ultimate aim of such research must eventually be to replace all of the cement in concrete with environmentally friendly alternatives. The term CEM0 is derived from the European cement types such as CEM1 and is used to describe a cementitious powder without cement. This paper will present results for types of CEM0 that have been made and also discuss problems which affected the models that were used to predict strength. These were caused by the variability of the secondary materials that are used to replace the cement. New models are being developed which rely solely on the observed properties of the materials such as their oxide contents. The paper will present initial findings from this new study and show how it could be used in a CEM0 production process.
