Carbon nanotubes (CNTs) in ultra-high performance concrete (UHPC): Dispersion, mechanical properties, and electromagnetic interference (EMI) shielding effectiveness (SE)

The incorporation of carbon nanotubes (CNTs) in Ultra-High Performance Concrete (UHPC) was investigated with regard to the dispersion, mechanical properties, and electromagnetic shielding effectiveness (SE). Dispersed CNT solution (0–2.0 wt%) was prepared by sonication and subsequent shear mixing with superplasticizer to achieve the high flowability for UHPC slurry. The dispersion method was effective to manufacture CNT-UHPC composite up to the...
