toxic materials (e.g., lead paint, silica) that are hazardous to workers. • Silica sand (crystalline) can cause silicosis, lung cancer, and breathing problems in exposed workers. • Coal slag and garnet sand may cause lung damage similar to silica sand (based on preliminary animal testing). • Copper slag, nickel slag, and glass (crushed
Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. Silica fume added to Portland cement allows it to pass the new stringent requirements. Since the destruction of the World Trade Center, new and higher standards were implemented. Without Silica Fume, we would not meet those standards.
