INVESTIGATION OF MANUFACTURE OF AGGREGATE AND RIPTRAP BY NUCLEAR MEANS,
Abstract
The objectives of the work reported herein were to investigate the feasibility of producing aggregate and riptrap by nuclear means and to verify and supplement size distribution data obtained by a photogrid method. This was accomplished by determining the size distribution, density, absorption, abrasion resistance, shape characteristic, rock types, and degrees of new fractures of material from 16 piles of ejecta from a trench excavated into the lip of the Danny Boy crater. Particle sizes were estimated by comparisons with the 1-foot grid spacing. Results of tests indicate that approximately 10 percent of the ejecta could be used for concrete aggregate after proper separation without secondary crushing. Physical tests and geologic examinations confirm that this ejecta would be acceptable as concrete aggregate. Thirteen percent of the ejecta was in the size range needed for riptrap. Fracturing of the ejecta was minor, and the dense particles would make good riptrap. All ejecta could be used with moderate sizing for jetty stone. (Author)
