Successful Cementene(TM) precast concrete trials

 

Versarien plc (AIM: VRS), the advanced materials engineering group, is pleased
to provide an update on the trials of Versarien's water-based graphene
admixture, Cementene(TM) in precast concrete mixes that have been carried out
by Banagher Precast Concrete Limited ("Banagher"), a precast concrete
manufacturer and supplier of precast concrete products to the civil
engineering and construction industries throughout the UK and Ireland.

 

The Company is pleased to report that preliminary results from the work
undertaken by Banagher have demonstrated that 20% of ordinary Portland cement
("OPC") can be removed from Banagher's typical precast concrete mix when
Cementene(TM) is added, whilst maintaining the compression strength of the
concrete. These initial results demonstrate the significant potential to
reduce CO(2) emissions without impacting the performance of the concrete.

 

The production of 1 kg of Cementene(TM) is estimated to generate approximately
1.44 kg of CO(2) emissions and approximately 5 kg of Cementene(TM) is used per
cubic metre of concrete.  The production of 1 kg of OPC emits approximately
0.8 kg of CO(2) and c.500 kg of OPC is used per cubic metre of Banagher's
precast concrete.  Therefore, the removal of 20% of OPC in the precast
concrete mix (approximately 100 kg) equates to a net saving of approximately
72.8 kg of CO(2) emissions per cubic metre of concrete poured.

 

Based on Banagher's average 60,000 cubic metre output of concrete per year,
the savings achieved in these trials mean that the incorporation of
Cementene(TM) could offer almost 4.4 million kg of CO(2) savings per year at a
cost the Company believes is competitive for this level of emissions
reduction.

 

Stephen Hodge, Chief Technology Officer of Versarien, said: "We are delighted
with the results that have been achieved by Banagher utilising Versarien's
Cementene(TM).  The use of Cementene(TM) has been demonstrated to offer a
substantial environmental benefit at a cost we believe is competitive.  We
look forward to continuing to work with Banagher and, in due course, other
concrete suppliers to role out Cementene(TM) enhanced concrete as soon as
possible."

 

Peter Deegan, Banagher Precast Concrete's Technical Director, said: "We have
been trialling many alternative additions to our concrete mixes in the drive
to net zero 2050, graphene in a liquid state is one such product.  Our new
UKAS/INAB accredited laboratory has allowed us to quantify any improvements in
performance based on compression testing, chloride migration, water absorption
and much more.  While still at an early stage, we are finding very positive
results and aim to continue with the research right through to scaling up at
our production plant.  We are confident that graphene will play a major role
in carbon reduction in the future."
