Abstract
A water impermeable liner, cap, or dam core for a containment basin for spent oil shale is made from a mixture of water and combusted oil shale having a particle size of less than about one cm, a residual organic carbon content of less than 1%, and at least 15% of its Mg/Ca/Fe carbonate minerals decomposed. A layer of the mixture is applied to the basin and/or top of the filled basin, compacted, and allowed to cure under conditions that minimize the likelihood of shrinkage cracking.
