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.

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.

1) According to "the polluter pays" principle, the system that generates the waste is responsible for declaring the
impacts 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 the
CO2–emissions from waste incineration) is 671 kg CO2-equiv.
