Harden and Self-Sensing Properties of Engineered Cementitious Composite Reinforced With Nano-Carbon

Abstract

Engineering cementitious composites (ECC) were discovered as a better alternative to conventional concrete due to their ability to achieve higher tensile strength. In subsequent years, additional studies were conducted to modify the materials in ECC to achieve a more sustainable and environmentally friendly composition. Incorporating nano-carbons such as fullerenes, carbon nanotubes, carbon nanoparticles, and graphene into ECC makes the advanced material highly advantageous. This chapter investigates the behavior of ECC reinforced with nano-carbons. The performance of ECC blended with nano-carbon is analyzed by comparing the fresh, mechanical and durability properties. In addition, the self-sensing and self-healing functionalities of ECC blended with nano-carbon are observed. The crack behaviour and healing performance of ECC are monitored due to the conductive ability of nano-carbon. Adding graphene in the range of 0.01 to 0.08% in ECC improves the young's modulus compared to conventional ECC.
