High Performance Fly Ash
High Performance Fly Ash
Cement Australia’s High Performance (HP) Fly Ash is a supplementary cementitious material (SCM) that enables reduced CO2 in concrete through increased replacement of GP Cement, without compromising strength performance.
HP Ash is a premium fly ash that fully complies with the requirements for Grade 1 Fly Ash in Australian Standard AS3582.1 – Supplementary cementitious materials for use with General Purpose and blended cement.
In addition to the benefits of Grade 1 Fly Ash such as improved later-age strength, workability and enhanced durability, HP Ash also provides low drying shrinkage and high early age strength. HP Ash is suitable for premixed and pre-cast concrete applications.
