Other Types of Cement
Additive Cement is produced by milling clinker, puzzolanic material (max. 19% by weight) and a given amount of gypsum. It hasn’t got any sub classes. Its early strength value is KC 32.5 within 28 days.
High Early Strength Cement is a special cement produced by milling clinker and a given amount of gypsum. It hasn’t got any sub classes. Its strength value is EYC 52.5 within 28 days period.
Portland Limestone Cement is produced by milling clinker, limestone and a given amount of gypsum. They are classified into two according to the amount of limestone in them. Type A includes 6-20% limestone by weight and type B includes 21-35% slug by weight. Portland Limestone Cement 28 is classified into six types according to their early strength periods within 28 days: PLC 32.5, PLC 32.5R, PLC 42.5, PLC 42.5R, PLC 52.5, PLC 52.5R. This cement type is newly adopted from European standards.
Portland Silica Fume Cement is produced by milling clinker, silica fume (max. 10% by weight) and a given amount of gypsum. This cement type is newly adopted from European standards and hasn’t got any sub classes. Its early strength value is PSFC 32.5 within 28 days.
It is made by grinding some solidification regulator (gypsum) with Portland cement clinker and mineral additives (pozzuolana) defined at their standardized ratios (max. 55%). It is a product that gains its strength by freezing after it is mixed with water.
It gains strength later than Portland Cement 42.5 and Portland Composed Cement A 42.5 R. Water/cement ratio is relatively high. It is more resistant to alkali-aggregate reaction and chemical external effects. Generally it is used in the repairs of constructions, making plaster and production of construction chemicals.

Plaster Cement is the cement that contains max 60% pzoolanic material. It does not have any sub classes. Its strength value is SSC 32.5 within 28 days period.
