Summary: Recycled aggregate concrete is an example of a sustainable construction material, especially in the presence of fly ash. This work was aimed to investigate the effect, if any, of recycled aggregate and/or fly ash on corrosion behavior of steel in cracked reinforced concrete. When used, as much fly ash as cement was added in the concrete mixture.

Coarse Aggregate for Portland Cement Concrete Coarse aggregates are particles greater than 4.75mm, but generally range between 9.5mm to 37.5mm in diameter. They can either be from Primary, Secondary or Recycled sources. Primary, or 'virgin', aggregates are either Land- or Marine-Won. Gravel is a coarse marine-won aggregate; land-won coarse aggregates include gravel and crushed rock.

Fly ash, especially Class F fly ash, is effective in three ways in substantially reducing alkali-silica expansion: 1) fly ash produces a denser, less permeable concrete, 2) when used as a cement replacement fly ash reduces total alkali content by reducing the Portland cement; and 3) alkalis react with fly ash instead of reactive silica aggregates.
