CEM I 42.5R

CEM I 42.5R

CEM I 42.5 R Portland Cement is a hydraulic binder according to SANS 50197. The main component is Portland cement clinker finely ground together with calcium sulphate, which controls the setting time for CEM I 42.5 R. Stringent production control during the entire production process ensures consistent high quality.

CEM I 42.5R Portland Cement is a rapid hardening cement ready for early strength or higher strength class. The cement is designed to meet a strength class 42.5R.

CEM I 42.5R Portland Cement can be used in applications where a higher early strength or strength class is required. It can be used in ready-mix concrete, precast concrete, or production of concrete goods.

Typical applications are concrete, mortar, masonry products and shotcrete.

• Higher earlier strength in counteracting the effects of cold weather conditions.
• Gives higher early strength for a given cement content.
• Earlier pre-stressing for pre-stressed concrete.
• Earlier stripping time for molds and formwork.
• Higher strength class of concrete.
• CEM I 42.5R is compatible with commercial chemical admixtures..
