Concrete accounts for 8% of global CO2 emissions and it's usage
is set to skyrocket in the coming decades as the world's
population grows and moves towards more urban environments. So
removing carbon from the process is a crucial part of the
climate mitigation challenge. And now, several start-up
companies have stepped up to meet that challenge.

(From The Carbon Herald)
The company’s technology is unique and revolutionary as it
replaces kilns – the most energy and fossil-fuel-intensive part
of the traditional cement manufacturing process. It uses an
electrolyzer instead of kilns that makes cement at ambient
temperature from a variety of abundant calcium sources.
The company makes calcium in a form that is ready to react with
silicon – the key element in sand. Normally limestone that
contains calcium is superheated inside a kiln to about 2,700
degrees using normally coal for fuel – a process that releases
tons of carbon dioxide into the atmosphere.

First Graphene announces major graphene-enhanced cement trial

[center]First Graphene announces major graphene-enhanced cement
trial with consortium that includes Breedon Cement, Morgan
Sindall and the University of Manchester[/center]
SNIPPET:
n June 2023, approximately 2,000 tonnes of graphene-enhanced
cement will be produced at Breedon that will be marked for use
in real world demonstrations. The cement’s performance as a
binder in mortar and concrete systems will be analyzed to assess
the performance improvement, prior to use in real-world
demonstrations by Morgan Sindall Construction, a leading British
construction and regeneration group.
Data from Breedon and FGR production sites has already been
analyzed by the University of Manchester and found
graphene-enhanced cement to both offset CO2 and demonstrate
potential mechanical benefits, even at graphene loading levels
less than 0.06%.
FGR has secured a one tonne order for a further trial in
graphene enhanced concrete, anticipated to be executed within Q4
2023. This one-off order, although not material from a
profitability point of view, is an important step in scaling up
to meet the increased requirements of the cement and concrete
segment, and continues to help build the Company’s pipeline of
revenue opportunities.
In Q4 2022, First Graphene secured a circa $13,000 grant from
Innovate UK’s Analysis for Innovators (A4i) competition to
develop a technique to quickly identify graphene in a sample of
concrete paste. This work was conducted with the UK’s National
Physical Laboratory a worldleading centre of excellence that
provides cutting-edge measurement techniques.
