The mechanical properties, microstructures and mechanism of carbon nanotube-reinforced oil well cement-based nanocomposites

High performance cement-based nanocomposites were successfully fabricated through the use of oil well cement filled with multiwalled carbon nanotubes (MWCNTs) as reinforcements. The dispersibilities of four dispersing agents for the MWCNTs were investigated and compared. The dispersed morphologies a...
