    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.

    Abstract translation: 本发明提出了将碳纳米纤维用于糊剂,砂浆和混凝土等水泥模具的可行性,目的在于使用这种复合材料来监测变形,以便检测由于没有嵌入或附着传感器的外部活动而引起的变形。 该程序基于在受到应力时改变碳纳米纤维/水泥复合材料的电阻。 基体与纳米纤维的接触应力和应力水平成比例变化; 在谈论智能结构时这无疑是有趣的。 该组合适用于控制结构振动,繁重的交通监控,建筑区域的运动检测以及实时建筑安防等等。
