With regards to energy saving, Aalborg invested in the
installation of a 400 KVA transformer to feed different
motors of the silo structure. Yearly average energy
consumption is about 4500 KWh/month, which is below
early estimations.
A safe and reliable automated operation
system
Unloading and loading cement operations are carried out
by an automated control system. The terminal manager
decides which silo to fill and controls the filling of each
silo’s different captors. When a silo is full, the loading
screws can be controlled and driven through a remote
management system, which can also carry out daily
maintenance operations.
Truck loadings are controlled by a weighbridge and the
required weight of cement or maximum weight of a truck
(44 t) can be set in the management system.
The fully-automated loading system could be
conducted by truck drivers alone. However, from a security
perspective, a terminal manager should be employed to
ensure the onsite safety of every subcontractor and driver.
The Rochefort terminal set safety instructions for daily
operation. For example, it is forbidden for a driver to climb
onto his bulk trailer via a little scale. A safety staircase is
instead required for drivers to get on top of trailers from
the first level of a loading station and drivers are asked
to go down to the control office to launch loading when
putting a spout in place.
Aalborg InWhite: Cementir Group’s white
innovation engine
An innovation programme for white cement, Aalborg
InWhite has the purpose of generating a prioritised and
actionable pipeline of global initiatives, with high potential
for customer value. This aims to provide new solutions for
well-known applications or completely new applications for
white cement based products.
Cementir Group creates customer value by developing
and redefining sustainable solutions in different levels
of customised services. “Cementir wants to challenge the
traditional way of looking at white cement as mainly
an aesthetic and architectural building material,” said
Di Marino. “There is untapped potential to further
develop a customer’s business with white cement that,
as a global leader, Cementir has the mission to make
available to its partners. “
In the last 12 months, a series of cutting edge white
cement application technologies have been triggered
under the new Aalborg InWhite Solution umbrella, fed by
Cementir’s global market knowledges, a strong industrial
network, and its authoritative research and quality centre,
based in Denmark.
It leverages the unique technical characteristics
of Aalborg White cement for some emerging but
rapidly expanding applications. These include ultra
high-performance concrete (UHPC) and glass fibre
reinforced concrete (GRC), which require high levels of
chemical purity and the excellent mechanical properties
of the concrete and which can be made with advanced
production technologies. Such technologies could
help to implement labour cost savings and simplify the
construction process, which fully support the megatrends
in society, including the following:

z
Reduced thickness to enable more efficient use of the
interior spaces of a building.
z
Surfaces produced in a single process to avoid
additional treatments.
