Type II/B-LL 32,5 R - Tipo II/C-M (P-LL) 32,5 R - LH - 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.

(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
- Reinforced and non-reinforced concrete
- Concrete for pouring structural facades
- Concrete for industrial flooring
- Concrete for foundations or underground works in non-aggressive environments
- Concrete with good pumpability and workability, also in case of absence of fine particles in the aggregate
- Soil stabilization and masonry work, constructing blocks, curbs, etc.
