Fly Ash | Cement Australia

Concrete-grade fly ash is a supplementary cementitious material that delivers improved later-age strength, workability and enhances the durability properties of concrete. It is commonly used as a 20% - 30% cement replacement in concrete. Grade 1 Fly Ash is used as a single product or may be blended to produce a Fly Ash Blended Cement.
