Zusammenfassung:Compositions for producing electrically conductive controlled low-streng th material and electrically conductive concrete are provided, comprising conventional components, but utilizing a non-standard, high carbon content, fly ash. One settable controlled low-strength material composition includes 1 %- 20% by weight of portland cement, 18%-85% by weight of fly ash having a carbon content of greater than 12%, and water such that the composition sets to a material having a compressive strength of 8.3 MPa or less. One settable concrete composition includes 1 %-30% by weight of Portland cement, 1 %-20% by weight of fly ash having a carbon content of greater than 12%, 40%-90% by weight of an aggregate, and water such that the composition sets to a concre te having a compressive strength of at least 13.8 MPa.
