Nanotechnology hits the road

After more than a decade of progress in other industrial sectors, the nanotechnology revolution has just begun to impact highway, road, and bridge materials and construction. The feasibility of Cyberliths, or Smart Aggregates, as wireless sensors embedded in concrete or soil is being studied. Concrete ills such as alkali-silica reactivity and delayed ettringite formation — the bane of concrete highways and bridges — are being studied at the molecular level using neutron scattering technology and other processes. more . . .
