-
Improved Workability: Fly ash particles are spherical and finer than cement particles, which enhances the workability of concrete. This makes it easier to mix, place, and finish the concrete.
-
Increased Strength and Durability: Fly ash reacts with calcium hydroxide in the presence of water to form additional cementitious compounds. This pozzolanic reaction improves the long-term strength and durability of concrete.
-
Reduced Permeability: The use of fly ash reduces the permeability of concrete, making it more resistant to water and chemical ingress. This is particularly beneficial in structures exposed to harsh environmental conditions.
-
Environmental Benefits: Utilizing fly ash in concrete reduces the need for cement, which in turn lowers carbon dioxide emissions associated with cement production. It also helps in the disposal of fly ash, reducing its environmental impact.
-
Cost Savings: Fly ash is often less expensive than cement, leading to cost savings in concrete production. This makes it an economically viable option for large-scale construction projects.
-
Coal Combustion: Coal is burned in a furnace to generate heat, which is used to produce steam for electricity generation. During combustion, mineral impurities in the coal are transformed into ash.
-
Collection: The fly ash is carried by flue gases and collected using electrostatic precipitators or bag filters. These devices capture the fine ash particles from the exhaust gases.
-
Storage and Handling: The collected fly ash is stored in silos or hoppers. It is then transported to concrete production facilities using pneumatic conveying systems or trucks.
-
Quality Control: Fly ash undergoes rigorous quality control tests to ensure it meets the required standards for use in concrete. This includes tests for fineness, chemical composition, and pozzolanic activity.
-
