Paper Title:
CFSC for Positive and Negative Temperature Sensing by Resistivity Measurement
  Abstract

Carbon fiber reinforced cement could sense its own temperature based on the temperature resistivity effect. In contrast with Portland cement, sulphoaluminate cement has much better freeze- resistance. As a result, carbon fiber sulphoaluminate cement composite (CFSC) has the superior potential to sense its own temperature than carbon fiber reinforced Portland cement in the negative and positive temperature, especially for the negative temperature range. The temperature resistivity effect of CFSC was discussed in the positive and negative temperature. And the lower and the upper temperature limit of temperature resistivity effect were investigated. The results indicated that temperature resistivity effect of CFSC was related to the hot expansion and the electric carrier activating. And the electric carrier activating was the primary influence factor. Temperature sensors could be made by CFSC based on its good temperature resistivity effect in positive and negative temperature range. Therefore CFSC has the advantage to sense positive and negative temperature by resistivity measurement.
