    摘要: Compositions for producing electrically conductive controlled low-strength 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 concrete having a compressive strength of at least 13.8 MPa.
