Crushed-rocks have uncommon shapes and are usu-ally randomly placed; hence, it is di cult to measure its permeability and inertial resistance coe cient. To nd the values for a cm crushed-rock, our research makes use of cm cement sphere in a wind tunnel experiment, where the boundary wind speed condition is given based on the
Core Laboratories: GRI Crushed Shale Analysis
GRI (Crushed Shale) Analysis. Then, by reducing the sample to a quantity of small particles, 0.5 to 0.85mm diameter, coring- and sampling-induced fractures are eliminated and pore pathways are greatly shortened so that efficient processing for pore liquid removal and quantification by distillation-extraction can be accomplished.

Methods Improve Shale Core Analysis
The added benefit of rock crushing is that it increases the surface area-to-volume ratio of the samples, greatly decreasing the time needed for fluid extraction, pres-sure diffusion and transient-state perme-ability measurements. However, there are situations where r ock crushing may be detrimental to the analysis, such as when the rock has an organic-rich, low clay maturity, poorly

THE SETTLEMENT OF CRUSHED ROCK A THESIS
The purpose of this research was to investigate these two problems by laboratory testing of the settlement of crushed rock, by studying the effect of a constant, sustained load on a point of rock bearing against rock, and by determining if creep and strain-related failure occur in rock which exhibits time-related settlement in the fragmented state.
An Experimental Investigation of Permeability Measurement
The permeability of crushed rocks is not only related to loading levels but also to grain diameters, style of arrangement. (4) To each grain diameter sizes, the permeability change of sandstone has a greater value than that of mudstone and limestone. The permeability of crushed mudstone shows much less than that of limestone and sandstone.

Rockdust. It functions the same way that the Earth does: during an Ice Age, glaciers crush rock onto the Earths soil mantle, and winds blow the dust in the form of loess all over the globe. Volcanoes erupt, spewing forth minerals from deep within the Earth, and rushing rivers form mineral-rich alluvial deposits.
