Disposal of Retorted Oil Shale from the Paraho Oil Shale Project-- final Report.
NTIS: PB/263-793 Available for Reference At Bureau Libraries :474 pages
A project to demonstrate the feasibility of retorting oil shale by the paraho vertical retort process was carried out at anvil points, Colorado, During 1974-76. The material which exists from the paraho retort is classified as a nonplastic silty gravel by the unified soil classification system. The particles have an apparent specific gravity averaging near 2.60 and a mass specific gravity averaging near 2.00. The material can be compacted by normal laboratory and field construction methods to about 90 to 100 pounds per cubic foot dry density depending upon the degree of compactive effort applied. The addition of moisture does not improve compactibility appreciably. When high compactive effort is applied, the retorted shale is classed as impervious to waterflow. The compacted retorted shale exhibits shear strengths in the same order as those observed for silty gravel soils. If the compacted material is cured prior to strength testing considerable strength can be obtained from cementing action. The amount of cementing developed is dependent upon heat treatment and other operating modes of the retort.
