Resource Efficiency
In the entire production process of Celitement up to
50 percent of the required energy can be saved compared
to the production of conventional Portland cement. Furthermore,
CO emissions can be reduced by up to 50 per-
2
cent. Thus, the energy and environmental balance of the
cement production could be improved considerably.
Barriers and Risks
The practical implementation of this new building material
in the industry might still take some years. Even though
Celitement seems highly promising, intensive research
work and testing trials must be conducted. A failure of
the material during construction could have serious consequences
for humans and the environment. Therefore, a
detailed examination of the physical and chemical characteristics
of the material is necessary before launching
such a new product. Only these extensive testing trials will
show whether Celitement can compete with conventional
cement in the long run.
Potentials
According to the Celitement GmbH, Celitement has numerous
advantages. Apart from the improved ecological balance,
Celitement features optimal material properties and
is compatible with conventional types of cement. Another
advantage is the well-known process engineering, since
the process of production of Celitement is already known
and widely tested in the manufacturing of cement or aer-
ated concrete.
In order to develop the new cement up to a stage of mar-
ketability, scientists of the KIT together with the industrial
partner Schwenk set up the Celitement GmbH. A pilot
plant on the KIT campus enables the conduction of first
tests, which are necessary for the long-term industrial implementation.
Starting in spring 2011, the pilot plant is to
supply 100 kilograms of Celitement daily. Already in 2014,
the new cement is to enter the market.
