Type I 52,5 R

This cement contains at least 95% clinker and up to 5% minor constituents, not including the addition of calcium sulfate and additives.

Known for its rapid early strength development, the cement conforms to the harmonized European standard EN 197/1 and displays the CE marking as required by European regulation 305/2011 (CPR).

(1) The values represent the level above (or below) the reasonably expected median values for the parameters indicated of BUZZI UNICEM cements belonging to the type and class named in the headers. These values are calculated on a yearly basis and take into account internal self-inspection data.

Current applications

  • Standard and non-standard reinforced concrete for works requiring high early and final strength
  • Concrete for prefabricated and/or prestressed structures, including with pre-tensioned tendons
  • Concrete for works requiring formwork removal shortly after pouring
  • Concrete for precast elements with or without accelerated curing
