Void ratio - Geotechdatafo
27 行 · 2 天前 · Void ratio is usually used in parallel with soil porosity (n) , which is defined as the ratio of the volume of voids to the total volume of the soil. The posoity and the void ratio are inter-related as follows: The value of void ratio depends on the consistence and packing of the soil. It is directly affacted by compaction.

2019-4-1 · 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 0.1–0.2 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.

2019-3-18 · It also doesn't matter much what size they are, at least until you get down to sand size. Sand runs about 30% void. So does big rock. But a mix of sand and big rock will end up with sand filling 70% of the voids in the big rock. so you get 30% of 30% void = 9%. You will lose some volume over the years from debris infiltrating in.
