摘要： Compositions are provided for increasing the electrical conductivity of concrete or controlled low-strength materials (flowable fill). One composition sets to produce a concrete and includes from 1% to 30% by weight of portland cement; from 1% to 30% by weight of fly ash having a carbon content as measured by loss on ignition of greater than 12%; from 40% to 90% by weight of an aggregate; from 0.1% to 20% by weight of carbon fibers; and water in a sufficient amount such that the composition sets to a concrete. Another composition is a self-compacting, cementitious flowable fill composition that includes from 1% to 30% by weight of portland cement; from 5% to 85% by weight of fly ash; from 0.1% to 20% by weight of carbon fibers; and water in a sufficient amount such that the composition sets to a material having a compressive strength of 8.3 MPa or less.

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.
