    摘要: Electric, self-heating concrete systems that uses embedded carbon macrofiber or nanofibers paper as electric resistance heating elements are disclose. The self-heating concrete systems may utilize the conductive properties of carbon macrofiber or nanofiber materials to heat a surface overlay of concrete with various admixtures to improve the concrete's thermal conductivity. The self-heating concrete systems allow concrete roadways or the like to be heated to above freezing temperatures in a freezing environment in a reasonable amount of time.

    摘要: A carbon nanofiber aggregate (CNFA) system and method provides self-sensing capabilities that can be used to detect strain, moisture, and temperature changes. The CNFA may include cement, aggregate, silica fume, high-range water reducer (HRWR), and/or carbon nanofibers. The metal meshes in the CNFA may be utilized to monitor the electric properties of the CNFA to detect strain, moisture, and temperature changes. The CNFA may be embedded in concrete structures to allow detection of strain, moisture, and temperature changes that may cause damage to structures. Several metal meshes may be embedded in the CNFA.
