Research progress on use of carbon nanotubes in cementitious grouting materials

Abstract

Carbon nanotubes (CNTs) have high strength and stable chemical properties, offering the potential to enhance the mechanical performance of cementitious grouting materials and finding wide applications in the field. This paper reviews the recent research on the application of CNTs in cementitious grouting materials. It introduces the basic structure of CNTs and commonly used dispersion methods in cementitious grouting materials, analyzing and summarizing hydration and microstructure, mechanical properties, and early shrinkage performance of carbon nanotubes-cementitious grouting materials, highlighting current research challenges. Additionally, the future research on CNTs in cementitious grouting materials is also envisioned.
