An experimental study on thermal analyses of crushed …

2019-4-1 · A crushed-rock layer with a smaller particle size has a greater albedo. The albedo of a painted crushed-rock layer is about 0.1–0.2 lower than the albedo of the paint because, at a rough surface, photons leaving the surface probably re-hit the surface. We found that this probability is about 0.4–0.6, increasing with the particle size of the .. uld crushed rocks absorb enough carbon to curb global ...2021-12-21 · Could crushed rocks absorb enough carbon to curb global warming? A little-examined form of geoengineering takes what rocks normally do—lock up carbon—and spreads it through the oceans.

Rock Fragmentation and Particle Size in Crushed Zones by ...
