Abstract
Conductive concrete mixtures are described that are configured to provide EMP shielding and reflect and/or absorb, for instance, EM waves propagating through the conductive concrete mixture. The conductive concrete mixtures include cement, aggregate, water, metallic conductive material, and conductive carbon particles and/or magnetic material. The conductive material may include steel fibers, and the magnetic material may include taconite aggregate. The conductive concrete mixture may also include graphite powder, silica fume, and/or other supplementary cementitious materials (SCM). The conductive carbon particles may comprise from about zero to twenty-five percent (0-25%) of the conductive concrete mixture by weight and/or the magnetic material may comprise from about zero to fifty percent (0-50%) of the conductive concrete mixture by weight.
