Magnesium chloride
Use in dust and erosion control
Road departments and private industry may apply liquid or powdered magnesium chloride to control dust and erosion on unimproved (dirt or gravel) roads and dusty job sites such as quarries. Its hygroscopy makes it absorb moisture from the air, controlling the number of small particles which become airborne. Similarly, magnesium chloride may be apply to sand or other floor materials to control dust. From Wikipedia.
