Hazard prevention and control in the work environment: Airborne dust

Any airborne flammable dust in sufficient concentrations can explode. Combustible dust on the ground may become airborne and increase and propagate an explosion which is started by flammable gas ignition. This can occur with vegetable and organic materials, as well as with metal and other oxidizable dusts. Static electricity can also pose hazards.

What makes concrete so strong is the chemical reaction that occurs when cement and water mix — a process known as hydration. "Hydration occurs when cement and water react," says Ulm. "During hydration, the clinker dissolves into the calcium and recombines with water and silica to form calcium silica hydrates."
