BASF - A New Generation of Highly Fluid Concretes
Zurich, October 2007: BASF’s Construction Chemicals
division is proud to introduce its Smart Dynamic
ConstructionTM concept, which allows the ready-mix
industry to reach increased energy efficiency, higher
concrete durability and better construction process
economy in order to reduce CO2 emissions and save time
and money. This concept is suitable for upgrading S4 and
S5 concretes to a higher performance level, with
self-compacting characteristics and the same ease of
production as standard concrete. In fact, it creates a
new concrete generation which combines the benefits of
traditionally vibrated concrete with those of
self-compacting concrete, is easy to produce and robust
in everyday use.
The Smart Dynamic Construction concept consists of a
robust mix design with less than 380 kg of fines, a
tailor-made GLENIUM® superplasticizer and the new and
unique RheoMATRIXTM product, a BASF-exclusive,
state-of-the-art Viscosity Modifying Agent (VMA) as the
key element of this revolutionary concept. Due to the
smart and self-organizing molecules of RheoMATRIX,
concrete mix-designs can now be optimized to achieve
unmatched and unique performance levels.
This innovative concept meets the existing and
continuously increasing demand for more fluid concretes
and offers the following benefits to the industry:
1. Economical:
Thanks to a unique mechanism of action in concrete,
savings of fines (<0.125mm) can be achieved. The stable
and highly fluid concrete is close to self-levelling and
thus permits installation without subsequent compaction.
The placing process is easy enough to be handled by just
one operator, which additionally saves up to 40% of work
time. This increases placing productivity by up to 5
times.
On top of that it is as easy to produce as standard
concrete because the mixes are less sensitive to changes
in water demand.
2. Ecological:
The low percentage of fines (e.g. cement), the
production of which causes CO2 emissions, improves the
ecological efficiency of the concrete.
Furthermore, this highly fluid concrete embeds the
reinforcement perfectly, giving it optimum protection
against external corrosion. This characteristic
increases the durability of the concrete and as a result
considerably extends the lifespan of buildings thus
equipped.
3. Ergonomic:
Thanks to its self-compacting characteristics this
concrete does not need to be vibrated, which means no
noise and no health hazardous vibrations for workers.
Additionally, the new mix design guarantees a type of
concrete with low stickiness, thus improving its
workability.
RheoMATRIX 100 consists of a mixture of water-soluble
polymers which modifies the rheological properties of
the concrete mix. Thanks to its tailored mode of action,
RheoMATRIX 100 imparts a level of viscosity within the
mix allowing the right balance between fluidity, passing
ability and resistance to segregation – apparently
opposing properties – to be achieved.
The innovative Smart Dynamic Construction concept
provides a smart technology to simplify the production
and control of a dynamic concrete which adds economical,
ecological and ergonomic values to the concrete. It
underlines the commitment of the Construction Chemicals
division to tailor-made solutions that drive the
concrete industry forward. In combination with local
technical support and the backing of the world’s leading
chemical company, this new concept has the potential to
move the market up to the next level of advanced
construction practice.
