Effect of Carbon Fiber Gradient Distribution on Heat Property of Electrically Conductive Cement Mortar

Abstract:

Abstract. Based on the electro-thermal property of carbon fiber-reinforced concrete, two groups of carbon fiber with equal quality dispersed in cement mortar deferring to layered and gradient distribution separately. The heat change of electro-thermal layer (with carbon fiber) and non- electro-thermal layer (without carbon fiber) of the two kinds of specimen was contrasted, and the corresponding thermal stress value among each layer was calculated theoretically. The results indicate that comparing with the carbon fiber layered distribution, carbon fiber gradient distribution decreases the thermal stress maximum of neighboring layers from 15.42MPa to 5.21MPa. The decrease of heating stress increases heat stability, by which can enhance cement mortar service life.
