Fly ash is a bi-product of coal based thermal power stations generated by the combustion of pulverized coal. Fly Ash is a pozzolanic material rich in silica & alumina and spherical in shape. The commonly known benefits of using fly ash in concrete are:
1. Workability
2. Reduced Permeability
3. Reduced Heat of Hydration
4. Improved Pumpability
5. Improved sulphate and Chloride resistance
6. Reduced Risk of Alkali Aggregate Reaction
7. Increases Long Term Strength
8. Better Concrete Finish
9. Reduced Bleeding and Segregation
10. Reduced Shrinkage and many more.
