2020-11-30  Conductive concrete is a cement-based composite that contains a certain amount of electronically conductive components to attain stable and relatively high conductivity. In essence, the aggregates normally used in concrete can be largely replaced by a variety of carbon-based materials to achieve electrical conductivity in conductive concrete. This is achieved while retaining the desired engineering properties, as indicated in Table 1. The conductivity is usually several orders of magnitude higher than that of normal concrete. Normal concrete is effectively an insulator in the dry state, and has unstable and significantly greater resistivity characteristics than conductive concrete,

ELECTRICALLY CONDUCTIVE CONCRETE

2021-3-1  Abstract: Concrete has been known for decades as a non-conductive material. However, electrically conductive concrete is an innovative type of concrete, which incorporates conductive material to form a contiguous network of current flow. Such materials include graphite powder, steel shavings and steel fibers. This new mix offer a spectrum of applications such as de-icing on bridges and runways, cathodic protection, radiant heating and electromagnetic shielding. This study aims at exploring means to prepare conductive concrete together with achieving better understanding of the properties and performance of conductive concrete made with three potentially conductive materials at different dosages. To meet this objective, concrete mixes were prepared with various presumably conductive materials. The testing scheme includes conventional fresh and hardened concrete tests as well as specialized conductive and permeability tests. Results reveal that producing conductive concrete is possible
