Zenyatta Ventures has signed an agreement with Larisplast to test the effect of adding graphene to concrete.
Larisplast is an Israeli business that specializes in concrete admixtures. Zenyatta and Larisplast have both received grant funding from the Canada-Israel Industrial R&D Foundation under the Ontario-Israel Collaboration Program to further test the effect of adding graphene generated from Zenyatta’s Albany graphite to concrete on a pilot scale.
On completion of pilot plant testing, a new joint venture company, owned by Zenyatta and Larisplast will market the admixture globally.
The collaboration is to develop a new concrete admixture with improved mechanical properties by adding Albany derived graphene. Albany graphite was found to exfoliate under sonication (sound energy process) much easier and with higher yields of graphene nano-particles than any other natural graphite types that were tested at Ben-Gurion University of the Negev in Israel.
Initial application testing shows that the addition of the graphene to concrete achieves a faster curing time and superior mechanical performance that inhibits premature failure and tolerates large forces produced during earthquakes or explosions.
Also, this new admixture has the potential to reduce the amount of cement that will be used in construction, thereby considerably cutting carbon dioxide emissions related to its production.
Aubrey Eveleigh, chief executive, Zenyatta Ventures says: “The graphene concrete application can potentially be a significant end use for our graphite material. It is not only environmentally friendly but has the potential to be a large volume consumer for our company.”
The global market size, in terms of value, of concrete admixtures is estimated to be $11.7bn in 2015 and is projected to reach $18.1bn by 2020
