3D printing, graphene partners trace rapid building template

A memorandum of understanding sets the stage for GrapheneCA, a New York-based commercial scale producer of graphene, to design an extruder and mixing system that could be embedded into the 3D-printing equipment of Apis Cor Co., San Francisco. Graphene is an advanced carbon agent emanating from nanotechnology and exhibits strong potential as an admixture for high performance concrete.

Researchers track graphene admixtures’ decade-long emergence

Sources: IDTechEX Research, Boston; CP staff

A new article, “Graphene: The evolving application landscape,” projects early prototype and semi-commercial prototype phases over the next 8-10 years for concrete, cement and asphalt additives bearing graphene or carbon nanotubes. That observation is consistent with lab or field demonstrations by a handful of admixture developers eyeing performance properties attainable in finished concrete through dosages of nano-scale cylinders with wall thicknesses the diameter of a single carbon atom.

Graphene rises from nanotech as a positive carbon factor for concrete

Scientists’ work with elements at the atomic level continues to yield promising concrete admixtures whose impact might one day approach that of polycarboxylate superplasticizers. As Concrete Products has observed in reports on Zenyatta Ventures Ltd. and EdenCrete Industries this past year, nanotechnology has led to identification and processing of concrete market-ready graphene, a single atom-thick layer of pure carbon derived from mineral or synthetic graphite.

The owner of a rare, volcanic graphite deposit in Ontario has entered an agreement with Israel-based admixture specialist Larisplast Ltd. to expand research on a processed agent, graphene, shown in preliminary testing to accelerate concrete curing time and impart mechanical performance suited to seismic or blast impact loads.
