www.brmca.org.ukpozzolanic materials are calcium, alumina and silica, as shown in a simplified form on the ternary diagram of Figure 1. On this dia-gram, the more calcium a pozzolanic material has, the closer it will be to the calcium corner of the triangle, and similarly with alumina and silica. CEM I is the most reactive material, as it is high in calcium,
