Name
CEM I 42.5R PORTLAND CEMENT
Technical purpose of product or process CEM I 42.5R Portland cement is a high-performance cement produced mainly from Portland clinker - with an average composition of 5%-100% clinker and 0%-5% other components in accordance with NP EN 197-1:2012. The clinker comes from Secil Outão. The cement does not contain any substance included on the Candidate List of Substances of Very High Concern (SVHC) above the limit for registration with the European Chemicals Agency, i.e. above 0.1 per cent (m/m). CEM I 42.5R Portland Cement is a high quality, high performance product, widely used in civil engineering works and in the manufacture of high and very high resistance concrete. It is particularly suited to works where a very high resistance is required on the first days after application. The main applications of this cement are: • ready-mixed or cast in-situ high and very high initial or final resistance concrete; • high resistance lightweight concrete; • early prestressed concrete; • concrete cast in cold weather; • prestressed lightweight and heavyweight prefabrication with high turnover of moulds and formwork; • sealing and grouting Name ofingredient Share oftotal weight Country of origin Additives 0 - 6 % Portugal Additives 0 - 6 % Spain Clinker 80 - 100 % Portugal Fillers 0 - 6 % Portugal Gypsum 6 - 20 % Portugal Natural aggregates 0 - 6 % Portugal

General comment on data set The Emidat EPD Tool v1.0.0 was used for LCA modeling and calculation. Background data was used from ecoinvent database v3.10. Elementary flows (energy and fuels, ancillary materials and waste) data was collected on production-process-level. Using the total output of the production process in 2022, elementary flows are assigned to 1 declared unit based on mass. No cut-offs were applied.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
