Sulfate-Resisting Portland Cement
Sulfate-Resisting Portland Cement B.S. 4027 : 1996 Class 42.5N
Sulfate-Resisting Portland Cement (SRPC) is a special purpose cement used where sulfates are present in concentrations that would damage Normal or RH Portland cement concrete.
Sulfate resistance is achieved by adjustments to chemical composition to limit the level of C3A in the SRPC.
The quality of all SRPC produced by the company is guaranteed to meet in full the requirements of British Standard 4027 : 1996 Sulfate-resisting Portland Cement, and the product is independently certified by the British Standards Institution. SRPC is made by fusing together at high temperatures a precisely controlled blend of very finely ground limestone, shale, and iron oxide to form cement clinker. A small quantity of gypsum is added to this clinker before grinding to produce the final fine powder – Sulfate-resisting Portland Cement. SRPC is produced in Platin, Co. Meath and is supplied in bulk.
Applications
Sulfate-Resisting cement is specified in concrete for certain sulfate exposure classes as described in National Annex to Irish Standard I.S. EN 206-1:2002 (see Table NA.7) Typical applications include concrete structures in sewage treatment works, and substructures on reclaimed ground. Guidance on the use of SRPC in reinforced concrete in contact with seawater is given in BS 6349. Due to the lower level of alkalis in SRPC, arising from its chemical composition, it is sometimes used to provide greater resistance to the risk Alkali-Silica Reaction in concrete. The suitability of admixtures for use with SRPC should be specifically mentioned on admixture suppliers literature.
