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
Self sensing carbon nanotube (CNT) and nanofiber (CNF) cementitious composites for real time damage assessment in smart structures
TL;DR: In this paper, the self sensing properties of cementitious composites reinforced with well dispersed carbon nanotubes and carbon nanofibers were investigated and compared with resistivity results of nanocomposites fabricated with “as received” nanoscale fibers at the same loading.
Journal ArticleDOI
Highly concentrated carbon nanotube admixture for nano-fiber reinforced cementitious materials
Zoi S. Metaxa,Zoi S. Metaxa,Jung Woo T. Seo,Maria S. Konsta-Gdoutos,Mark C. Hersam,Surendra P. Shah +5 more
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.
