Type II/B-LL 32,5 R - Tipo II/B-LL 32,5 R - Buzzi Unicem Italia

Type II/B-LL 32,5 R

This cement may contain between 65-79% clinker and between 21-35% limestone. A maximum of 5% minor constituents is permitted. The percentages indicated do not include additions 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).

CGreen

Product with a lower environmental impact formulated to uphold the principles of sustainability and offer construction solutions that meet the latest environmental standards. The criteria used to define the CGreen line are based on the GWP (Global Warming Potential) indicator, which is included in the Environmental Product Declaration (EPD) to quantify the Carbon Footprint of cement and the entire supply and production chain.
The percentage of recycled content has also been identified for each cement to define the circularity indicator by cement type.
