Summary
Open and unpopulated areas are exposed to wind, rain and other physical agents which wear away the matter composing them and dust or fine matter is lifted up by the wind to form large dust whirls that damage the environment, traffic and health.
For dust control, Calcium Chloride has been used effectively because it is able to absorb and retain humidity in the environment and it does not evaporate. As is common knowledge to all, one of the most common forms of controlling dust is to sprinkle it with water with the disadvantage of easy evaporation due to the temperature or wind.
The amount of Calcium Chloride used depends on two conditions: the climate and the type of land. Its application varies from 0.6 to 1.0 Kg/m2.
It is applied as follows: If it is liquid, a tank truck is used and if it is solid, it is manually spread as evenly as possible.
Its use is recommended for: Parking lots, railway yards, warehouses for materials, mines, sporting fields without grass, bullrings, etc. | |
