ABSTRACT
Manufactured cements are those made in a cement factory. Where a mineral material is included, it is generally added to the cement clinker at the grinding stage. The notation used for these manufactured cements contains the prefix letters CEM. When a concrete producer adds an addition such as pfa or ggbs to CEM I Portland cement in the mixer, the resulting cement is known as a mixer combination, and is denoted by the prefix letter C. Cements and combinations in general use are listed in Table 2.17. Further information on the different types and use of cements is given in section 3.1.1.
