| Use advice for data set | Scope: This core-EPD relates to 1 kg of Sika® ViscoCrete®-510 P, a superplasticizer and water reducer in powder form, produced in Leimen, Germany and is representative for the year 2023. The results in this core-EPD were calculated using an LCA-tool verified by IBU in 2023. System boundary: Declaration type with respect to life cycle stages covered according to clause 5.2 EN 15804+A2 is cradle to gate with modules C1–C4 and module D (A1–A3, A4, A5, C and D). Modules taken into account: A1 Production of preliminary products A2 Transport to the plant A3 Production including provision of energy, production of auxiliaries and consumables and waste treatment A4 Transport from the construction site to the installation site A5 Installation, admixtures applied into the building during A5 phase operations. At this stage, an impact of the production and treatment of installation residue equal to 1% of the product is considered. C1-C2-C4-D The 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. One scenario is considered for the final treatment of the waste: 100% disposal (C4), modelled by landfill process where admixtures end their life cycle.Module D accounts for benefits that are beyond the defined system boundaries. Credits are generated during the incineration of the installation scrap in module A5. | ||
| Technical purpose of product or process | For the production of dry-mixed mortars and concrete for applications like floor screeds, underlayments, and grouts. Solid particles are very effectively dispersed in the mix, enabling high water reduction and/or improved flowability of mortar and concrete, and related benefits like Portland cement clinker reduction/substitution, Reduced mixing, placing and compacting efforts, Increased density and strength, Reduced shrinkage, and enhanced durability. | ||

| General comment on data set | Sika® ViscoCrete®-510 P is a superplasticizer and water reducer in powder form based on Sika® ViscoCrete® polycarboxylate polymer technology. For the placing of the product on the market in the European Union/European Free Trade Association (EU/EFTA) (with the exception of Switzerland) Regulation (EU) No. 305/2011 (CPR) applies. The product needs a declaration of performance taking into consideration EN 934-2:2009+A1:2012, Admixtures for concrete, mortar and grout - Part 2: Concrete admixtures - Definitions, requirements, conformity, marking and labelling, and the CE marking. For the application and use the respective national provisions apply. | ||

| Technology description including background system | Sika® ViscoCrete®-225 P is a powdery material that is produced from a liquid intermediate based on polycarboxylate ether (PCE) through a targeted combination of drying, dispersing and/or comminution processes. Technical data: Sika® ViscoCrete®-510 P meets the requirements of EN 934–2, Table 3.1/3.2. Declared unit: The EPD refers to the declared unit of 1 kg of concrete admixture (superplasticizer) powder applied into the building in accordance with IBU PCR 04-2023 part B for concrete admixtures. The max. permissible dosage of Sika® ViscoCrete®-510 P is 0.5 mass % by weight of binder. | ||
