Publication Detail Adaptation Of Crushed Rock Analysis

Legacy crushed rock analysis, as applied to unconventional shales, has shown great success in evaluating total porosity and water saturation over the previous two decades. The procedure of crushing rock into small particles improves the efficiency of fluid recovery and grain volume measurements in a laboratory environment.

An Experimental Study On Thermal Analyses Of Crushedrock

Apr 01, 2019 Fig. 2 shows the albedo of the crushed-rock layers coated with different colors during the course of days. The most striking characteristic in Fig. 2 is that the albedo of the crushed-rock layers is about 0.10.2 lower than the albedo of the paint. The reason is that the photons leaving a rough surface, like a crushed-rock layer, can be re-captured by the surface.
