Jup, Klinker, Zement, Beton mit ihren vielen vielen durchaus unterschiedlichen Anforderungen und Anwendungen inkl Bestandteilen und PureGRAPH war und ist meine Top Idee für PureGRAPH. Warum? Im Prinzip, weil mit PureGRAPH / Graphene nicht nur etwas bessere Ergebnisse möglich sind, sondern signifikante.
Womit soll ich anfangen? Hmmm, egal, nimm diesen Bericht aus 2018 (!):
https://www.hannovermesse.de/de/news/...dert-die-rissbildung-in-betonNun lassen wir alle anderen Betrachtungen beiseite. Recycling Beton, Einbringung CO2 in Beton, Spezialanwendungen, 3DCP usw. und machen einen grossen Sprung nach 2022, UK:
https://www.ice.org.uk/areas-of-interest/...-carbon-concrete-routemapDort in dem Bericht aus 2022, unter Punkt 6: New Technologies:
".... Apart from already existing materials, the emphasis should
be placed on the research into new cement constituents such
as synthetic SCMs or additives such as graphene and biochar.....
Und einen längeren Auszug (sry@Klimawandel ;) )
... Market opportunities
There must be a market opportunity for a technology for it to
reach commercialisation. The highest level of opportunity is
when the technology can be produced at scale and compete
with existing alternatives due to demand-pull, rather than
technology-push drivers. Vertical integration within large
established market participants spanning different levels of the
supply chain means that entry by new companies is relatively
more challenging.
Company maturity
Where a new technology is being developed by a new company,
the company maturity is at the lowest level. As the technology
is developed, or adopted by larger companies, the company’s
performance record and market share with the technology
grows to the point where the technology is being provided by
industry-leading companies with strong track records.
For a new technology to achieve market penetration, all
of these factors will need to be addressed. While technical
performance and inclusion in technical standards are often
the first items sought by product developers and users, it is
important to consider the wider commercial context of the
product to achieve significant emissions reductions through the
use of lower-carbon concretes.
This is well illustrated by the fact that there are many more
cements specified in the Eurocodes than are currently
commercially available in the UK. In this case, the technical
certification has not been sufficient to increase market uptake
and several of the other commercial readiness indicators will
need to be addressed (primarily supply chain, industry skills and
regulation through policy) to bring these cements into common
practice in the UK....
Das ist also FGRs / Breedon / Morgan Sindall / Innovate UK roadmap.
