Abstract

Micro/meso scale modification can bring big changes in macroscale property. The addition of nanofillers makes materials strong, durable and multifunctional/smart. This paper aims at studying mechanical property, durability, electrical property, electromagnetic property and piezoresistivity of concrete with nano silica(NS), carbon nanotube(CNT), botryoid hybrid carbon material (BHCBM), nano graphite platelet(NGP) and nano-tip material(spiky spherical nickel particles), respectively. Results demonstrate that the compressive and flexural strengths of concrete show significant increases with the increasing contents of NS. The addition of CNT obviously enhances the transport property of concrete. The BHCBM endows the excellent electrical conductivity with concrete. Both shielding effectiveness and electromagnetic wave absorbing performance of concrete can be achieved by adding NGP. The concrete with nano-tip material has ultrahigh piezoresistive response to stress and strain.
