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

The Hazards Of Silica Dust. Crystalline silica is a common mineral in the earth’s crust and is found in many types of rock including sand, quartz, and granite. Silica is present in both work and non-work environments, and exposure to crystalline silica dust has long been known to cause a disease called silicosis. When you inhale crystalline silica the lung tissue reacts by developing fibrous

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
