Fly Ash
Fly Ash is a product of burning finely ground coal in a boiler to produce electricity. Fly Ash is generally light tan in color and consists mostly of silt-sized and clay-sized glassy spheres. This gives Fly Ash a consistency somewhat like talcum powder. Fly Ash is a pozzolan, a siliceous material which in the presence of water will react with calcium hydroxide at ordinary temperatures to produce cementitous compounds. Because of its spherical shape and pozzolanic properties, Fly Ash is useful in cement and concrete applications.
The addition of Fly Ash in concrete saves a lot of cement and fine aggregate, reduces water consumption, improves the workability of concrete mixtures, enhances the pumpability, hydrothermal and thermal expansion of concrete, improves the impermeability of concrete, and increases the ground modification of concrete.
