Valid to 26.03.2020 Verification The CEN Norm EN 15804 serves as the core PCR Independent verification of the declaration according to ISO 14025 internally x externally Prof. Dr.-Ing. Horst J. Bossenmayer (President of Institut Bauen und Umwelt e.V.) Dr. Eva Schmincke (Independent tester appointed by SVA) Dr. Burkhart Lehmann (Managing Director IBU) Product Product description Cement is a hydraulic binder. It is a finely ground inorganic material which, when mixed with water, forms a paste which sets and hardens by means of hydration reactions and processes. After hardening, it retains its strength and stability even under water. The declared cement is Portland cement CEM I 52,5 N according to /EN 197-1/. Application The main application of cement is in the production of concrete. [Clinker is produced from raw materials such as limestone and clay which are crushed, homogenized and fed into a rotary kiln. The raw materials are sintered at a temperature of 1450oC to form new compounds. The components of clinker are mainly calcium oxide (CaO) and silica (SiO2), and small amounts of aluminium and iron oxide. ] Anhydrite: 4-5 % [Anhydrite is added to control the setting time of the cement. ] Limestone: 2-3 % Minor constituent: up to 0,2 % Technical Data Portland cement CEM I 52,5 N has compressive strength according to the standard class 52.5 according to /EN 197-1/. Constructional data Reference service life This study covers the production stage information (from A1 to A3) of the product. As no use stage is declared, the reference service life for cement is irrelevant. Name Value Unit Strength class acc. to DIN EN 197-1 52.5 N/mm2 Base materials / Ancillary materials Portland cement CEM I 52,5 N consists primarily of clinker and other cementitious materials. The average composition of 1 tonne of Portland cement is as follows: Clinker: 88-97 % 2 Environmental Product Declaration SIA CEMEX – Portland cement CEM I 52,5 N LCA: Calculation rules Declared Unit The declared unit is 1 tonne of Portland cement CEM I 52,5 N. Declared unit Name Value Unit Declared unit Conversion factor to 1 kg 1 0.001 t - System boundary Type of the EPD: cradle - to-gate. The system boundary of the EPD follows the modular structureaccording to /EN15804/. The Life Cycle Assessment therefore covers modules A1 to A3: extraction and processing of raw materials, transport ofraw materials to the factory gate and internal transport and cement production. As cement is an intermediate product with many different final uses modules A4, A5, B and C are not declared in the scope of this EPD. Comparability Basically, a comparison or an evaluation of EPD data is only possible if all the data sets to be compared were created according to /EN 15804/ and the building context, respectively the product-specific characteristics of performance, are taken into account. LCA: Scenarios and additional technical information As this EPD focuses on the manufacturing stage of Portland Cement CEM I 52,5 N only (modules A1-A3), it was not necessary to develop product level scenarios for this cradle - to - gate assessment. Thus, no information on modules A4, B1-B7, C1-C4 & D is provided in this section of the EPD. 3 Environmental Product Declaration SIA CEMEX – Portland cement CEM I 52,5 N LCA: Results The table below give the LCA results for environmental impacts, resource use as well as output flows & wastes categories for the modules that are declared in this study.

The net value (excluding the CO2–emissions from waste incineration) is 671 kg CO2-equiv.
