Product
Product descriptionCement 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/.
ApplicationThe main application of cement is in the production of concrete.
Technical DataPortland cement CEM I 52,5 N has compressive strength according to the standard class 52.5 according to /EN 197-1/.Constructional dataName Value UnitStrength class acc. to DIN EN 197-1 52.5 N/mm2
Base materials / Ancillary materials Portland cement CEM I 52,5 N consists primarily ofclinker and other cementitious materials. The average
composition of Portland cement is asfollows:Clinker: 95-100%[Clinker is produced from raw materials such aslimestone and clay which are crushed, homogenizedand fed into a rotary kiln. The raw materials aresintered at a temperature of 1450oC to form newcompounds. The components of clinker are mainlycalcium oxide (CaO) and silica (SiO2), and smallamounts of aluminium and iron oxide.Minor additional constituents as anhydrite, limestone or dusts: 0-5%
Reference service lifeThis 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.

LCA: Calculation rules
Declared UnitThe declared unit is 1 tonne of Portland cement CEM I 52,5 N.
Declared unitName Value UnitDeclared unit 1000 kgConversion factor to 1 kg 0.001 -
System boundaryType 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.
ComparabilityBasically, 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.

1) According to "the polluter pays" principle, the system that generates the waste is responsible for declaring theimpacts of waste processing until the end - of - waste stage is reached. However, for transparency reasons, the indicated value includes the CO2–emissions from waste incineration (gross value). The net value (excluding theCO2–emissions from waste incineration) is 671 kg CO2-equiv.
