Hi TWHM
I thought I had seen Talga say that they were testing electrically conductive concrete,
This was 2 years ago in the Business update - July 2016 announcement,
Talga also talk about upcoming results from the testing of the electrically conductive concrete in the April and May 2017 announcements
July 2016 Ann,
3. Cement Additive for Conductive Concrete
Different types of graphene used in published cement mix trials has been shown to improve strength, impermeability, resistance to surface abrasion and most importantly for Talga, to make concrete electrically and thermally conductive.
A conductive concrete can be warmed cheaply using low voltage electrical current applied directly to the concrete, compared to the currently expensive methods of underlaying hot water pipes and electrical wires. Large domestic markets exist for underfloor heating and snow-free driveways while large industrial markets include ice-free roads/rail crossings, bridges, footpaths, outdoor stairs and airport aprons.
Talga has been collaborating with a European cement company to produce a graphene cement additive that suits current market formulations, distribution and handling procedures. Talga will look to undertake a joint research program with a European university that provides product trial data to support industry adoption and partnerships. Work to date has shown the Talga product can also incorporate the 'solid waste' of graphene processing as an additive to some products.

April 2017 Announcement
Next Steps
The thermal conductivity results set the stage for Talga to advance its various discussions with international players in the building and construction sector. Talga will continue to progress its product and commercialisation strategy in this sector using prototype test results as the catalyst to initiate joint development programs with global suppliers in the industry, similar to the agreement recently announced with Chemetall, part of BASF.
A range of in-house concrete formulations were prepared and tested against multiple performance criteria, which included, but was not limited to, thermal conductivity and flow properties. Results for other concrete performance attributes are being finalised to provide test data on material strength, electrical conductivity and rheology

May 2017 Announcement,
• Builds on previously announced successful concrete thermal conductivity results
with electrically conductive concrete work underway
Electrical conductivity tests are underway and results will be reported once analysed. Talga will continue to progress its product and commercialisation strategy in the construction sector using these prototype test results as the catalyst to initiate joint development programs with global suppliers.
