Castle Sulphate-resisting Cement is packed Portland-fly ash low alkali cement manufactured to comply fully with the requirements of BS EN 197-1 CEM II/B-V class 32,5R (+SR). BS8500 classifies this cement with a +SR suffix to signify its enhanced sulphate resistance. Sulphates in soils and groundwater's react with the tri-calcium aluminate (C3A) present in most Portland cements causing expansion and ultimate deterioration of the concrete. In order to minimise this reaction the composition of Sulphate-resisting is manufactured to have reduced levels of C3A. Sulphate-resisting is produced using carefully selected raw materials. Strict quality control throughout each stage of the manufacturing process ensures that a consistent final product is achieved.

Key Features
  • Equivalent in sulphate resistance to Sulphate-resisting Portland Cement (BS4027)
  • Lower water demand than Portland Cement (CEM I) mixes
  • Improved chloride resistance
  • Meets the requirements of Building Research Establishment Special Digest 1 for all sulphate conditions except class DC-4m
  • Meets the requirements of BS8500 : 2002 Concrete -Complimentary British Standard to BS EN 206-1.Reduced Alkali Cement - declared mean equivalent Na2O of less than 0.6%
  • The colour may be darker than Portland cement (CEM I)

Sulphate-resisting is recommended for use in all concrete, mortar and grout below ground or where sulphates are present in concentrations likely to lead to deterioration. (Except for class DC-4m)Marine Concrete: The use of Sulphate-resisting improves the durability of concrete in marine environments. Moderately low heat: The use of Sulphate-resisting reduces the heat evolution of concrete for given cement content. Alkali silica reaction: The use of Sulphate-resisting minimises the risk of alkali silica reaction.

Strength Ultimate concrete strengths using Sulphate-resisting are similar to those obtained with Castle Cement or Castle Multicem. Early age strengths are likely to be affected. It is therefore recommended that prior to full scale production trial mixes are carried out to ensure all requirements for the mix are fulfilled.
