Portland pozzolana cement is a type of blended cement which is produced by mixing pozzolana content with the OPC clinkers at the time of grinding. ... The mixture is then finely ground in a ball mill or grinder. This method is most preferred as it poses no difficulty in production and produces a homogeneous and uniform (±3%) blend.
