| Use advice for data set | Scope: This core-EPD relates to 1 kg of SikaRapid®-800 ECO, (a hardening accelerating admixture according to BS EN 934-2:2009+A1:2012), manufactured at Sikas plant in Watchmead, Welwyn Garden City, AL7 1BQ, United Kingdom 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 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 (weighted average distance calculated on deliveries of this product from 2022-23) 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 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 wooden pallets in module A5. | ||
| Technical purpose of product or process | SikaRapid®-800 ECO 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 | SikaRapid®-800 ECO is a liquid hardening accelerator for concrete and mortar, designed specifically for enhancing the performance of concrete with high levels of supplementary cementitious material (SCM), such as GGBS and PFA. It promotes early and late age strength development without negatively influencing final strengths. | ||

| Technology description including background system | The manufacturing of concrete admixtures involves the blending of liquid and/or powders in aqueous solution. Raw Materials are shipped in IBCs, Big-Bags, bags, or bulk to the Sika plant and stored in Silos, Tanks or inside our warehouses until their use. During production these different RM materials are weighed, dosed, and blended according to a recipe. The result goes under quality control and after positive result is then packed and delivered or transferred to finished goods storage tanks for later packaging and deliver. Admixtures can be delivered in bulk (tankers) or in several types of packaging (IBCs, Drums, Bottles, cans, etc.). Technical data: SikaRapid®-800 ECO meets the requirements of BS EN 934-2:2009+A1:2012, Table 7. Declared unit: The EPD refers to the declared unit of 1kg of concrete admixture (hardening accelerator) applied into the building with a density of 1.19 g/ml in accordance with IBU PCR 04-2023 part B. | ||
