Abstract
Esta invención plantea la viabilidad del uso de nanofibras de carbono en matrices cementicias: pastas, morteros y hormigones, a fin de usar dichos composites en la monitorización de deformaciones para detectar su propia deformación al verse sometidos a acciones externas sin ningún tipo de sensor embebido o adherido. El procedimiento se basa en el cambio en la resistencia eléctrica del material cementicio con adición de nanofibras de carbono al ser sometida a tensiones. Se realiza un cambio proporcional a la resistencia de contacto de la matriz con la nanofibra con el nivel de tensiones a que es sometida, lo cual es indudablemente interesante a la hora de hablar de una estructura inteligente. Este composite puede aplicarse para control de vibraciones estructurales, monitorización de tráfico pesado, detección de movimiento en estancias y seguridad de edificios, en tiempo real, entre otros.
