Using cement as a rock dust. | Permaculturenews
Cement is not "rock dust", like "crusher dust" is (by-product of screening/crushing blue-metal (basalt) to fine construction grades). Cement is a "hydraulic" extract from ancient coral reefs. Hydraulic cements (e.g., Portland cement) harden because of hydration chemical reactions that occur independently of the mixture''s water content; they can

Rock may also need to be specifically placed to control dust generation, the generation of acidic or otherwise potentially toxic water runoff, or seepage to groundwater.Other criteria are required to separate potentially problematic rock, and a carefully considered plan to manage it must be prepared and implemented (eg, INAP, 2014).Historically, with poor quality water from early uranium mines

Maintenance of Incombustible Content of Rock Dust in
The ETS requires mine operators to increase the incombustible content of combined coal dust, rock dust, and other dust to at least 80 percent in underground areas of bituminous coal mines. The ETS further requires that the incombustible content of such combined dust be raised 0.4 percent for each 0.1 percent of methane present.

Comets are made of frozen gasses and bits of rock and dust. The solid part of most comets can be up to 10 miles across. As a comet gets close to the sun, the heat causes the comet’s frozen gasses to turn into a cloud of vapor and dust. The cloud can be thousands of miles across. Solar winds cause this vapor cloud to trail out behind the comet
