Fly Ash instead of Cement
Fly ash is a pozzolan — to make cement, just add water. Combined with lime and water, it forms a mixture that is similar to portland cement. But it is just an additive, rather than a replacement for portland cement. It is routinely used in 15 percent to 25 percent dosages in ready mix.

Why use Fly Ash and Slag in Concrete?
Fly ash particles are spherical and are smaller in size than cement. Fly ash can only be activated when cement is being used as well. When cement reacts with water, it produces lime, which reacts with fly ash, which produces CSH (Hydrated Calcium Silicate). The CSH is the same cementing product as Portland cement.
