I was looking for any concrete laced with graphene news, and I found this story. I'm posting it because it has a graphite company, Zenyata (ZEN on the Israeli exchange) that is developing graphene for concrete, and is investable if you have access to the Israeli market (I don't).
I am not sure how these graphite to graphene plays will work out against the other mass production forms that don't use graphite and have showed promise recently, but there are a bunch of them out there.
Zenyatta Ventures Graphene – Wonder material makes concrete stronger
By now most investors have heard of the new wonder material called graphene. This single carbon atom super material can be derived from natural graphite. Graphene can truly be called the material of the future as it is 200 times stronger than steel but very flexible, and it conducts electricity better than any other material. Graphene is so thin that it may be thought of as two-dimensional and can be mixed with all manner of materials to increase strength. Due to these and other properties, it has the potential to literally revolutionize several industries. Thousands of researchers all over the world are working to develop many disruptive and game changing graphene applications. One such revolutionary application is the addition of graphene to cement creating a strong and environmentally “green” concrete.
Zenyatta Ventures Ltd. (TSXV-ZEN) partnership with Ben-Gurion University (‘BGU’) and Larisplast Ltd. is putting the junior mining company on the leading edge of a graphene concrete application because of its purity and crystallinity derived from a rare igneous (or volcanic) style of graphite. The deposit, called Albany, is especially well suited to form graphene from graphite as noted by scientists from BGU and Lakehead University in Thunder Bay.
Zenyatta is traded on the US OTC under ticker ZENYF. Company is actually Canadian-based (their Albany graphite deposit is located in Northern Ontario). Its main listing is on the Toronto Stock Exchange. The NR you made reference to is regarding a partnership with an Israeli University named Ben-Gurion. Here's the 5-year chart on ZENYF (been quite a ride!)...there's a number of active SI Zenyatta boards that you can also easily find if interested:
also just ran into this interview uploaded a few days ago with CEO Aubrey J. Eveleigh of Zenyatta Ventures Ltd. (OTCQX: ZENYF)....basically they have an extremely rare form of graphite called "volcanic graphite" (vs. the flake type graphite that is very abundant). Mr. Eveleigh really gets into the graphene interest for their graphite at 1:30....says that every single corporation is working on graphene applications right now (at 2:07)....at 3:16 gets into the concrete application for graphene and their graphite:
Zenyatta's graphene oxide tested by U.S. materials firm

Mr. Aubrey Eveleigh reports
ZENYATTA NANO-MATERIAL SUCCESSFULLY TESTED IN ADVANCED SILICON-GRAPHENE ANODE FOR NEW LITHIUM ION BATTERIES BY A U.S. BASED ADVANCED MATERIALS COMPANY
Zenyatta Ventures Ltd.'s graphene oxide material has been successfully tested by a leading U.S.-based advanced materials company (U.S. Co.) developing silicon-graphene anodes for the next generation of lithium-ion batteries. Preliminary results show ease of processing with Zenyatta's graphene oxide and similar electrochemical performance compared with the control material that is currently being used by U.S. Co. The superior dispersion qualities and good electrochemical performance of the company's graphene oxide are desirable properties for this silicon-graphene battery application. Zenyatta's high-purity graphite was recently converted to graphene oxide by Dr. Aicheng Chen, professor at Lakehead University, and then sent to the U.S. Co. for testing as an advanced nanomaterial in a new lithium-ion battery.
Lithium-ion batteries are widely used globally for portable electronic devices and electric vehicles. Unfortunately, lithium-ion batteries still lack the required level of energy storage to completely meet the demands of such applications as electric vehicles. A new silicon-graphene composite anode enables higher-capacity and faster-charging batteries that could meet consumer demand for increasing power and range.
Aubrey Eveleigh, president and chief executive officer of Zenyatta, commented: "Given the present limitations on the existing lithium-ion battery, the world needs to develop a superbattery. Silicon-graphene is the next-generation anode being developed for batteries by many advanced material companies. Zenyatta's graphene oxide has properties that make it a suitable material to be used with silicon in these next-generation lithium-ion batteries. While silicon has many times the capacity of graphite, it cannot be used alone due to rapid degradation. A significant amount of research has been carried out to encapsulate silicon in a graphene material to enhance the cycle life while also increasing charge capacity and durability for advanced lithium-ion batteries."
Mr. Eveleigh added: "We are very excited with the potential of our graphene to play a key role as a component of the next-generation batteries. The adaption of silicon-graphene-based anode batteries could further accelerate the fast-growing market for energy storage, especially for the automotive sector. Having a consistent and high-quality raw material source in North America for an end-user's supply chain is critical in order to maintain long-term quality control for product specifications."
U.S. Co. will continue to carry out advanced testing on Zenyatta's graphene oxide for use in lithium-ion anode composite material. Additional testing will include the determination of the following:
Aqueous dispersion quality;
Compatibility with processing method and yield;
Characterization of the composite material.
Zenyatta Ventures is developing the Albany graphite deposit situated in Northeastern Ontario, Canada. The deposit is a unique type of igneous-hosted, fluid-derived graphite mineralization containing highly crystalline carbon in two large breccia pipes. The company is collaborating with several partners in Asia, Europe and North America using its high-purity graphite for lithium-ion batteries, fuel cells and graphene. The outlook for the global graphite and graphene market is very promising, with demand growing rapidly from new applications. It is now considered one of the more strategic elements by many leading industrial nations, particularly for its growing importance in high-technology manufacturing and in the emerging green industries such as electric vehicle components.
The Albany graphite deposit is situated 30 kilometres north of the Trans-Canada Highway, power line and natural gas pipeline near the communities of Constance Lake First Nation and Hearst. A rail line is located 70 kilometres away with an all-weather road approximately 10 kilometres from the graphite deposit. The world trend is to develop nanomaterial products for technological applications that need extraordinary performance using ultrahigh-purity graphite powder at an affordable cost. Albany graphite can be upgraded to approximately 99.9 per cent carbon with very good crystallinity without the use of aggressive acids (hydrofluoric) or high-temperature thermal treatment, therefore having an environmental advantage over other types of upgraded high-purity graphite material.
