Recycling of old building materials with HPc and UHPC bindersystems

In our fast-moving times, old houses, some of
them historical houses, are being brutally torn
down to make room for new, more modern,
larger, higher and often not more beautiful but
more effective new building designs. Very
often there is no time left and there is often no
will to secure the valuable and reusable old
building material.

The end of an old building is a heap of rubble
that is only suitable as gravel material for the
subbase material of streets.

The architects in particular could campaign
for the reuse of such materials. It would be
entirely possible to reuse these old materials
in modern design concepts and to save some
valuable raw materials.

This year we will start some attempts to
combine UHPC with a variety of old used
materials. We are very sure that this is
possible without any problems, both in terms
of statics and construction. Of course, with
UHPC we can copy old materials in
appearance and design extremely precisely,
in some cases this is certainly sensible and
necessary. However, we want to reuse old
materials and hand them over to a new
design function. Even building rubble could
become a very interesting concrete material

in combination with UHPC. We also want
to give architects and designers new design
options using old and ultra-modern materials.
