The new edition of BASF's innovation podcast
"Chemistry of Innovations" talks about the applications of
construction chemicals for extreme conditions. With the help of
innovative chemistry it's possible to add special properties to
concrete.

In the construction process of the Swiss Gotthard Base Tunnel,
which will one day be the longest train tunnel in the world, concrete
has to fulfill conflicting requirements: On the one hand wet concrete
must not harden while being transported through the mountain for
several kilometers, on the other it has to harden in an instant, when
being sprayed onto the tunnel wall. Additives to concrete uses such
as accelerators and plasticizers make it possible. In addition, a
sprayable fire protection mortar prevents concrete from exploding
when being exposed to temperatures above 500 degrees Celsius.
