Enhancement behaviours of carbon nanotubes reinforced cement based grouting materials under dynamic loading
Source abstract
Abstract
Carbon nanotubes (CNTs) reinforced cement based grouting material is an important part of green manufacturing industry. Our previous research showed that this material can effectively enhance the impact resistance of rock matrix. In this study, We conducted a comprehensive study and quantitative analysis of the changes in pore structure of this material under impact conditions. Dynamic impact testing and computed tomography (CT) revealed that CNTs significantly increased the cement content in the sample by 79.11%. The CNTs group exhibited higher internal pore density and uniformity, effectively suppressing the formation of dynamic cracks in the sample. Compared to Non-carbon nanotubes (Non-CNTs) cement-based materials, the peak dynamic stress of the CNTs group increased by 4.76% to 21.54%, while the porosity decreased by 57.26%.This study further refined the enhancement behaviors of carbon nanotubes reinforced cement based, and making outstanding contributions to engineering practice.
