The influence of preparation method and electrode on properties of carbon fiber electrically conductive concrete

摘要

This paper studied the influence of preparation method and electrode on properties of carbon fiber electrically conductive concrete by testing flexural strength and electrical resistance. Carbon fiber electrically conductive concrete is prepared by using dry mix method and wet mix method, the electrodes of which are stainless steel mesh and stainless steel sheet. The results show that the wet mix method of carbon fiber electrically conductive concrete is better than the dry mix method. The stainless steel sheet used as electrode in electrically conductive concrete is better than the stainless steel mesh. The long-term electrical resistivity of carbon fiber electrically conductive concrete is a constant value.
