Stabilizing coal-water mixtures with portland cement

Patent ·
OSTI ID:5485637
;
A coal-water mix is described for use as a fossil fuel containing up to 70% by weight coal particles, based on the total weight of the mix, stabilized by the presence in the mix of up to 15% by weight, based on the weight of the coal, of portland cement, the portland cement stabilizing the mix by greatly extending the time that the coal particles remain in suspension, thus eliminating problems of transporting and storing the mix which result when the coal particles come out of suspension.
