Abstract

The invention proposes the viability of using carbon nanofibers for cement moulds such as pastes, mortars, and concretes, with the purpose of using such composites to monitor deformations in order to detect the deformation thereof due to external activities with no sensor embedded or attached. The procedure is based on changing the electrical resistance of the carbon nanofiber/cement composites when subjected to stress. A proportional change is made to the contact stress of the matrix with the nanofiber and the level of stresses to which it is subjected; this is undoubtedly interesting when talking about an intelligent structure. The composite is adaptable to control structural vibrations, heavy traffic monitoring, movement detection in building areas, and building security in real time, amongst others.
