PatentDOI
Highly dispersed carbon nanotube-reinforced cement-based materials
TL;DR: In this paper, a composite cement material is prepared from cement material and carbon nanotubes, wherein the carbon-nanotubes are present from about 002 wt % to about 1 0 % based on the weight of the cement material.
Journal ArticleDOI
Multi-scale mechanical and fracture characteristics and early-age strain capacity of high performance carbon nanotube/cement nanocomposites
TL;DR: In this article, the reinforcing effect of highly dispersed multiwall carbon nanotubes (MWCNTs) in cement paste matrix has been investigated, and the MWCNTs were effectively dispersed in the mixing water by using a simple, one-step method utilizing ultrasonic energy and a commercially available surfactant.
Journal ArticleDOI
Highly concentrated carbon nanotube admixture for nano-fiber reinforced cementitious materials

TL;DR: In this paper, a method for preparing highly concentrated multwalled carbon nanotube (MWCNT)/aqueous/surfactant suspensions in cement based materials is presented, thus reducing the volume of the resulting admixture that is required in cement-based materials.
Book ChapterDOI
Nanoscale Modification of Cementitious Materials
TL;DR: In this paper, an effective method of dispersing carbon nanotubes (CNTs) in cement matrix was developed, and significant improvements on the macro and nano-mechanical properties of cement paste were observed with the incorporation of CNTs.
Journal ArticleDOI
Carbon nanofiber cementitious composites: Effect of debulking procedure on dispersion and reinforcing efficiency
TL;DR: In this paper, the effect of surfactant to carbon nanofibers (CNF) ratio on the dispersion of two types of CNFs, one subjected to a new special debulking method and one with minimal debulkation process, was investigated.
