Sulphate resistant cement
Sulphate resistant cement – designed for aggressive environments
A cement with enhanced sulphate resistance
The sulphate resistant cement (SVC III/A 32,5 R) was launched into the Czech market in August 2001. In Czech Republic European harmonized standards for cements EN 197-1 are valid since March 2002. From March 2004 - as a preparation for joining European Union - marking of sulphate resistant cement has been changed to CEM III/A 32,5 R – svc.
This cement is especially for aggressive environments. The concrete made from this cement is typically used in foundations, basements, and waste-water systems as well as for standard ready mixed concrete. The composition of this cement is different than the average cement due to the limited content of calcium aluminate in the clinker and limited content of clinker in cement. This is significant for limiting the reaction between tricalcium aluminate (C3A) and sulphate which damages concrete. The portland clinker within sulphate resistant cement is specifically produced at Cement Works Mokra for this product and for special cement being used for concrete roads.
Sulphate resistant concrete is designed for aggressive and corrosive environments. The biggest customers are large ready-mix companies and the manufacturers of pre-cast elements such as pipes. Currently, there are no European standards for sulphate resistant cement. For this reason, sulphate resistant cement CEM III/A 32,5 R is being produced, certified and brought to the Czech market according to general European harmonized standard for cements EN 197-1 and according to tighten requirements.
