The concept of cement admixture using nano graphite platelets had been proposed by other institutes and so far only Larisplast is going ahead with Zen to bring it forward with a pilot plant.It all comes to the cost of such material available to the market at this stage and it,s still too expensive to consider even at a cost of $10 p/g(which is not even available at this price at present)Besides,they are not even real nano graphite-graphene materials but just thin-graphite.Not good enough according to Dr. Ian Flint.
