| Use advice for data set | This environmental product declaration shows the life cycle assessment of the production of of Portland-limestone cements BL II/A-L 52,5 R (BL II/A-L 52,5 R) at the Sagunto plant of Holcim Spain. Type of EPD: cradle-to-factory gate The system boundaries include the manufacture of BL II/A-L 52,5 R including the extraction of raw materials through to the finished product at the factory gate. The product stage includes: Module A1: Extraction and processing of raw materials. Module A2: Transport of raw materials to the factory gate and internal transport. Module A3: Manufacture of cement or cementitious components. The construction stage, the usage stage and the disposal stage are not taken into account in the life cycle assessment for cement. |
| Technical purpose of product or process | BL II/A-L 52,5 R is used as a binder in the manufacture of concrete and mortar. |

| General comment on data set | BL II/A-L 52,5 R is a white Portland-limestone cement BL II/A-L 52.5 R which is produced and monitored in accordance with EN 197-1 and UNE 80305. This cement is a hydraulically hardening binder for the production of concrete and mortar. It consists of a mixture of finely ground, non-metallic, inorganic components. After adding water to the cement, a suspension (cement paste) is formed, which solidifies and hardens both in air and under water due to the onset of a hydration reaction and remains permanently solid. The composition of the product corresponds to the specifications of EN 197-1. |

| Technology description including background system | BL II/A-L 52,5 R is manufactured at the Sagunto plant. Production of Portland cement clinker Limestone, marl, clay or their natural mixture, are required for the production of Portland cement clinker. These starting materials are mined in quarries, pre-crushed and transported to the nearby cement works. There they are homogenized into an intermediate product, with additional natural or secondary corrective substances being added to fine-tune the chemical composition. In the subsequent heating process, the Portland cement clinker is produced from the intermediate product. The firing process takes place in a rotary kiln, where the material is thermally converted at around 1450 °C and then rapidly cooled. The finished clinker is stored in silos. Cement Production To produce the ready-to-sell cement {name}, the cement components are finely ground and combined. A sulfate carrier is added to control the setting behavior. The Sagunto plant is ISO 9001 certified. |
