Abstract

In this research, the use of conductive nanoadditions, such as carbon nanotubes (CNT) and graphite products (GP), in cement specimens has been studied to develop strain sensing and heating functions. For this purpose, cement paste specimens with addition of 1% CNT and 5% GP have been fabricated and heating tests have been performed in direct current (DC) and alternating current (AC) at 20 V and 40 V. In addition, the influence of temperature on the strain sensing tests in the range from 0 °C to 60 °C has been studied, obtaining good results in both techniques. Therefore, these materials offer a very interesting alternative in structural monitoring and may have applications in the heating of infrastructures such as bridges and airports, avoiding the use of corrosive substances.
