What dust be used for? Rock dust is a byproduct of the quarrying industry and results from rock crushing. In the industry it is known as blue metal, cracker or crusher dust. Landscapers use rock dust for filling holes, bedding paving stones and mixing with cement. . Soil can benefit from the minerals found in rock dust.
concrete, or construction rubble can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs. This fact sheet describes dust controls that can be used to minimize the amount of airborne dust when using crushing machines as listed in Table 1 of the Respirable
The environmental impact of concrete, its manufacture and appliions, are effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.

· Concrete Recycling • Breaking, removing and crushing hardened concrete from an acceptable source. • Old concrete pavements often are excellent sources of material for producing recycled concrete aggregate (RCA). • This webinar focuses primarily on RCA from existing pavements (not mixed CD waste). 6
Long time exposure with concrete dust can cause damage to the human lungs and also crystalline silica can cause silicosis that is incurable. In addition, silica dust can form scar tissue in the lungs by reducing the ability to take oxygen. I hope this article on "How to stop concrete dusting" remains helpful for you.
