| Use advice for data set | Scope: This core-EPD relates to 1 kg of Sika® ViscoCrete®-111 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. | ||

| 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®-111 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®-111 P is 0.5 mass % by weight of binder. | ||
