| Use advice for data set | Scope: This core-EPD relates to 1 kg of Sika® ViscoCrete®-4097 with a density of 1.08 g/ml, a high-performance superplasticizer, produced in Kirchberg, Switzerland and is representative for the year 2022. 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 withmodules 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 ofthe production and treatment of installation residueequal to 1% of the product is considered. The building deconstruction (demolition process) takes place in 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 whereadmixtures 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 | Sika® ViscoCrete®-4097 is used as a constituent material to produce concrete. It can be used in combination with other Sika admixtures and can be successfully used in mix designs utilizing supplementary cementitious materials. | ||

| General comment on data set | Sika® ViscoCrete®-4097 is a high range water reducing admixture utilizing Sikas ViscoCrete polycarboxylate technology. Sika® ViscoCrete®-4097 meets the requirements of SN EN 934-2: plasticizer for concrete. Sika® ViscoCrete®-4097 is designed for use in ▪ Recycled concrete RC-C, RC-M ▪ Concrete with highly absorbent aggregate granulation ▪ With increased coarse air in the fresh concrete ▪ Concrete with long transport distances ▪ At elevated temperatures ▪ Pumped concrete ▪ Self-compacting concrete SCC ▪ Exposed concrete ▪ Concrete with maximum water reduction ▪ Waterproof concrete (white tank) This all-season additive has the advantage of ▪ Highest water reduction ▪ Highest consistency maintenance ▪ Reduced coarse air in fresh concrete ▪ Good flowability ▪ High impermeabilities and strengths ▪ Improved creep and shrinkage behavior ▪ Improved durability ▪ Harmless for reinforced and prestressed concrete structures For the purposes of this EPD, Sikas Industrie Neuhof 9, 3422 Kirchberg, Switzerland manufacturing site was selected. The product needs a declaration of performance taking into consideration SN EN 934-2+A1, 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. | ||
