摘要: … The results of some fundamental investigations on the bulk electrical properties of carbon fiber cement composites (CFCCs) are presented with the prospect of developing a new nondestructive testing method to assess the integrity of the composite. The addition of carbon fibers to portland cement-based concrete or mortar improves the structural performance and at the same time significantly decreases the bulk electrical resistivity. This makes CFCC responsive to interrogation by electrical methods. Three different electrode …
