Hanson 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.
