Portland limestone cement

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.
