摘要: In this work, several nanomaterials have been used in cementitious matrices: carbon nanofilaments (either multiwall nanotubes or nanofibers), nanosilica and nanoclays. The physico-chemical behavior of these nanomaterials at three different levels has been analyzed: cement paste, mortar and concrete. It has been determined the setting times, the workability, the mineralogical structure and the dispersion of the nanomaterials in the cement matrix by ESEM/EDX, the percentage of hydration by TGA and the mechanical …
