| Use advice for data set | Scope: This verified EPD entitles DBC and EFCA to bear the symbol of the Institut Bauen und Umwelt e.V. It exclusively applies for the product groups referred to for plants operated in Belgium, Finland, France, Germany, Italy, Netherlands, Norway, Poland, Spain, Sweden, Switzerland, Turkey and the United Kingdom by companies that are members of DBC and members of EFCA National Associations in these countries and for a period of five years from the date of issue. It involves a Model EPD where the product displaying the highest environmental impact in a group was selected for calculating the Life Cycle Assessment. Please refer to the EFCA website www.efca.info for a list of National Associations and the DBC website for a list of DBC member companies (www.deutsche-bauchemie.de). The application of this EPD is only possible for member companies of DBC and member companies of EFCAs member associations and only for specific formulations with a total score below the declared maximum score for a product group according to the associated guidance document. System boundary: Modules A1, A2, and A3 are taken into consideration in the LCA: A1 Production of preliminary products; A2 Transport to the plant; A3 Production incl. provision of energy, production of packaging as well as auxiliaries and consumables, and waste treatment; A5 Installation, admixtures applied into the building during A5 phase operations and packaging disposal; C1 - C2 - C4 - DThe building deconstruction (demolition process) takes place in the C1 module which considers energy production and consumption in terms of diesel and all the emissions connected with the fuel-burning process. After the demolition, the admixture is transported to the end-of-life processing (C2 module) where all the impacts related to the transport processes are considered. For the precautionary principle and as the worst-case scenario, disposal is the only end-of-life scenario considered. This is modeled by the landfill process (module C4) where admixtures end their life cycle. Module D accounts for benefits that are beyond the defined system boundaries. Benefits are generated during the incineration of wastes in module A5, which are declared in module D. | ||
| Technical purpose of product or process | Concrete admixtures are used as constituent materials for the production of concrete, mortar and grout (unreinforced concrete, reinforced and prestressed concrete, site-mixed and ready-mixed concrete, precast concrete). Their application should be in line with the manufacturers technical documents and Declaration of Performance. | ||

| Technology description including background system | Concrete admixtures are usually manufactured by mixing ingredients (together) in batch mode and filling containers for dispatch. The process follows quality standards outlined in EN 934-6:2019. Technical data: Plasticizers and superplasticizers must comply with the general requirements of EN 934-1:2008 and the additional requirements of EN 934-2:2009+A1:2012. The corresponding requirements in line with EN 934-1:2008 and EN 934-2:2009+A1:2012 must be maintained. Declared unit: This EPD refers to the declared unit of 1 kg of installed concrete admixture for optimized concrete (group A) with a density of 1-1.6 kg/l in accordance with the Concrete admixtures, 10/2023 (PCR checked and approved by the SVR). The maximum dosage of Plasticizers and Superplasticizers is 2 % by mass related to the cement content in the concrete. Depending on the application, a corresponding conversion factor such as the density to convert volumetric use to mass must be taken into consideration. The Declaration type is according to EN 15804: Cradle to gate with options, modules A5, C1–C4 and D. | ||
