Thomas Swan has signed an exclusive agency agreement with Concrene.
Thomas Swan’s Graphene Nano Platelet (GNP) products have been tested in a number of concrete dispersions by Concrene and have shown compressive strength improvements of greater than 20% with loading of less than 1% by weight.
Highways contractor Amey and its client Kent County Council will be testing Gipave, an Italian graphene-based asphalt supermodifier said to extend pavement life.
The trial is taking place as part of the Association of Directors of Environment, Economy, Planning & Transport (ADEPT) Smart Places Live Labs programme funded by the Department for Transport of the UK.
Directa Plus has reported that a deal to supply a special grade of its G+ graphene product, known as ITC1, to its partner, Iterchimica. The G+ product is the differentiating component of Gipave, an asphalt super-modifier developed by Directa Plus and Iterchimica and follows successful trials in Italy and the UK.
The agreement signed by the companies provides for the exclusive supply of the G+ graphene product to Iterchimica in the asphalt and bitumen sector worldwide and is for an initial duration of three years.
A team of researchers at the Rice University lab of chemist James Tour has designed a ‘Green’ process that produces pristine graphene in bulk using waste food, plastic and other materials. According to the team, this process can help facilitate a reduction of the environmental impact of concrete and other building materials.
The new process can turn bulk quantities of just about any carbon source into graphene flakes. The process is quick and cheap; Tour said the “flash graphene” technique can convert a ton of coal, food waste or plastic into graphene for a fraction of the cost used by other bulk graphene-producing methods.
Directa Plus has announced that it is planning to launch a trial of graphene-enhanced asphalt at an international airport.
The six month trial would take place at Rome's Fiumicino airport on taxiway Alpha Alpha, a high traffic taxiway used for class E and F intercontinental aircraft such as Boeing 777s and Airbus A380s, the company said.
