High Performance and Ultra High Performance Cementitious
materials are currently at the leading edge of
construction materials. Their excellent mechanical and
durability properties have qualified them for uses
outside of the traditional scope of concrete
applications.
The problem of waste management, both industrial and
nuclear is of growing concern at a European level. It is
likely to become one of the key issues of the next
century.
Existing solutions (involving traditional concrete or
other materials) are not fully satisfactory either on a
property basis or on a cost basis.
In all cases, the main problem consists in the
degradation by leaching of water that can be present
inside or outside of the waste. This aggression will be
the cause for the decrease in the stability and perennity
of the waste and may cause severe problems.
HPC/UHPC whose mechanical and durability properties are
being intensively studied are potential excellent
candidates for mid-range industrial application in the
field of waste management. Nevertheless, their ability
to sustain long term leaching as not yet been studied in
depth.
It is the intention of the consortium (including 5
organisations and 3 countries throughout Europe) to
develop a high level scientific programme in order to
understand and model the behaviour of HPC/UHPC vis a vis
water leaching.
The phenomena at stake are complex and may differ from
what is observed in traditional concretes. That is why
the know-how of European research centres specialised in
concrete and cementitious materials, together with
industrial companies research divisions having developed
and promoted HPC/UHPC will be joined to fully
characterise and model the thermodynamical and kinetical
phenomena at stake. Innovative scientific techniques
will be introduced and developed in the programme due to
the complexity of the problem. They include NMR (with
the help of an educational research centre specialised in
solid NMR applied to cementitious materials) and
impedance measurements.
Finally, a thermodynamical / kinetical model will be
proposed on the basis of physical-chemical analyses
carried out on 7 HPC/UHPC mixes submitted to different
water leaching durations (between O and 18 months). This
model will be implemented in the form of numerical
simulations validated by test results.
This will help the consortium to propose lifetime
modelling of HPC/UHPC regarding leaching and to prepare
their midterm industrial application to the field of
waste management. Data for the preparation of future
codes will also be provided.
The main deliverables of the project are:
to measure and understand microstructural and transfer
properties of 7 HPC/UHPC mixes before and after long-term
degradation by water leaching (representative of natural
conditions)
to understand thermodynamical and kinetical processes
at stake in the course of the long term water aggression
and to trace back their origin into the mix design.
to perform numerical simulation of degradation and
lifetime modelling of the HPC/UHPC mixes
to provide data for the introduction of HPC/UHPC into
codes
to lay ground for perennial HPC/UHPC industrial
solutions in the field of industrial or nuclear waste
management
The consortium comprises the following partners. A major
contractor (Partner 1 and co-ordinator, France) will
produce and characterise UHPC and implement modelling of
leaching behaviours. A cement producer (Partner 2,
Sweden) will produce HPCs. A Research centre (Partner 3,
Sweden) specialised in cement chemistry will perform
physical-chemical analyses of cementitious materials. A
research centre specialised in concrete microstructural
analysis (Partner 4, Spain) will perform controlled
degradation of test materials and analyse their
microstructure. A University (Partner 5, France)
specialised in NMR will contribute innovative techniques
applied to cementitious materials.
