The differences between these cement types are rather subtle. All five types contain about 75 wt% calcium silicate minerals, and the properties of mature concretes made with all five are quite similar. Thus these five types are often described by the term "ordinary portland cement", or OPC.
Ordinary Portland Cement. NCF introduced its Ordinary Portland Cement as "NorCem". It is a highquality, costeffective building material. It is produced by inter grinding of high grade clinker with high C3S content and right quality gypsum in predetermined proportions.
