Abstract
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.
