Nanotechnology enables sustainable and durable concrete infrastructure

Prof. Xianming Shi (University of Miami) discusses various nanotechnology-based innovations, such as #graphene oxide (GO), which unlocks the value of #coal fly ash in #concrete. A patented #geopolymer technology that hinges on the use of GO in the waterglass activated ash to produce a "greener" cementitious binder is presented, as are other nanotechnology enabled innovations in concrete #materials.
